Kayla and Hailey met in high school, and have followed each other through both college and adult life. When Hailey and the triplets agreed that they would choose different MoH's for each others weddings due to the sheer amount of sisters they have, Kayla was a no brainer! The two FaceTime every other day, share almost everything with each other, and Kayla is considered like another sister to the Bialas family. Kayla has been a huge help with all wedding planning and Hailey, truly, couldn't be more grateful. Throughout Kayla and Hailey's friendship together, there has not been a single man in Hailey's life besides Brad that Kayla liked, but then she met Brennan. Her original words to Hailey were, "don't f*** this up!"

Aidan is Brennan’s younger brother, the “man in the middle” of the Harrington siblings, and his obvious choice for Best Man. Aidan and Brennan have been best friends since day one and have created many lifelong memories together. Many of which come from sharing a room together growing up, yelling at the TV playing video games, wrestling in the basement, playing basketball in the driveway, weekends at the racetrack, or when Brennan got to coach Aidan in volleyball. In their childhood, while sharing a room, they could often be heard dying laughing while screaming Sponge Bob quotes loud enough to keep up the rest of the house. When the couple called the Harrington siblings after getting engaged, Hailey was elated to not only be engaged but because she is finally going to have a brother in Aidan.

Ashley is the oldest of the Bialas triplets, and the triplet that Hailey got to name. Realistically, though, 5 year-old Hailey actually wanted to name her Mowgli after her favorite movie at the time, The Jungle Book. That idea was shut down very quickly by her parents, so Hailey settled for Ashley which was a group of characters from the 90's Disney cartoon, Recess. Regardless, the two are wildly similar in so many ways. They look alike, sound alike, act alike and cannot get enough of each other. When Ashley goes over to her friends apartment, it is even an ongoing joke that upon her arrival they say, "Oh, Hailey we didn't know you were coming." Ashley is often seen at Hailey and Brennan's house since she has moved back to Illinois after going to college on the East Coast to play hockey. Hailey could not be happier that her sister is back within driving distance, and as far as Hailey is concerned none of her sisters should ever move states away from her again.

Zach and Brennan met at St. Ambrose University their freshmen year. One of their first memories as friends was rather than watching the Seahawks beat down the Broncos in the 2014 Super Bowl, they opted to watch Pitch Perfect with some friends instead. Zach soon became Brennan’s roommate and the two have been best friends since. A fun fact that the two realized early in their friendship is that Zach is named after a school in Des Plaines called St. Zachary, which is where Brennan attended school K-8th grade. Zach and Brennan lived together at St. Ambrose, a townhome in Schaumburg, and a house in Glen Ellyn. The two were roommates for over 4 years and have lived with Sean Dermody and Morty Begrlind over the years. Hailey and Zach met when in the backyard of the Glen Ellyn house as he was getting back from coaching hockey. Hailey grew up around the rink, and was happy Zach was able to have already enlightened Brennan enough on the sport to have a novice understanding.

Sarah, a.k.a "P-Nut", is the second oldest of the Bialas triplets, and is the chillest (and funniest) person you will ever meet. Sarah is Hailey's fiercest protector, mainly because Hailey would make Sarah sleep in her room with her after watching scary movies and it is doubtful that don't Sarah would ever want to do that again. At the beginning of Brennan and Hailey's relationship, Brennan was invited on the Bialas family vacation. Sarah was not happy about this one bit, because the couple had only been dating for four months. Fast forward to the trip, and Brennan and Sarah were going on excursions together without Hailey and Sarah realized this relationship was going to last well past four months. Sarah was actually the first sister to find out Brennan and Hailey were getting engaged, and was told not to tell her other sisters yet. Obviously, though, by the time Brad called the other two, Sarah had already let the cat out of the bag!

Morty and Brennan met at St. Ambrose University their freshmen year. They played high school volleyball against each other but were then teammates at SAU. Morty was the dedicated DD in college that would get everyone home from the bars. Brennan typically would criticize Morty’s driving since Brennan grew up racing, but hoped that Morty could get everyone home safely. Morty’s family is like a second family to Brennan, and have had both Brennan and Hailey up to their Michigan lake house. In the early days of Brennan and Hailey’s relationship, Morty could be seen being the couples favorite third wheel. These two have had so many fun memories together that simply cannot be forgotten or explained. Morty is also a Bears fan… (I know, sad).

Syd is the baby of the Bialas family, and the youngest of the triplets. Hailey and Syd are more similar than they like to admit sometimes, but truly the two are inseparable. When Hailey and Brennan began dating, Syd was up late one night and went with Brennan on a 2AM Taco Bell run. The two talked for hours, and grew very close very quickly. It was since then you would hear Syd gush over how she hopes to find a partner like Hailey found in Brennan. On family vacation, apparently Hailey and Brennan were being cute and Syd noticed. She started stalking them from afar to not blow her cover, and was taking tons of candid photos of the two. Once the engagement happened Syd finally shared the photos with them, and it is safe to say they was worth waiting for.

Sean and Brennan met at St. Ambrose University and lived together at SAU and in Glen Ellyn. The two have become great friends and share a passion for the Green Bay Packers. This creates a level playing field for Bears vs Packers trash talk among the 4 former roommates. Sean and his girlfriend, Holly, started dating around the same time that Brennan and Hailey started dating. The two couples love to spend time together, and when the two gentlemen moved in with their girlfriends following the Glen Ellyn house they both got dogs around the same time. Sean & Holly’s dog, Ellie, has become great friends with Brennan & Hailey’s dog, Piper, which gives them even more of a reason to hangout.

Cailyn, also known as CaiHarr, is Brennan's one and only sister and the baby of the Harrington family. Growing up Cailyn watched Brennan play a lot of volleyball and developed her own passion for the game at a young age. Brennan took her under his wing and started training her as his setter protege. Cailyn and Brennan could typically be found playing volleyball in the gym, outside, or even in the basement if no gyms were available. Cailyn ended up having the most career assists out of the Harrington siblings and went on to play at the University of Dubuque. When Hailey and Brennan called the Harrington siblings after he popped the question, Hailey mentioned she was finally getting a brother in Aidan, and Cailyn immediately responded that she is finally going to have a sister!

Andy is Brennan’s first racing friend. The two started racing each other at Chicago Indoor Racing in their junior leagues and soon made the jump too outdoor racing and joined Team CIR. The Dunne and Harrington families became super close during long weekends at the racetrack, which ultimately led to Andy & Brennan becoming best friends. You would typically find these two in the Dunne’s basement playing Forza or Call of Duty while eating Cheez It Party Mix or Noodles & Company, which was their favorite place to grab a bite to eat growing up. Adventures at Ty Warner park were also a staple in their friendship.

Emily and Hailey met in college at Illinois State University, and in adulthood lived down the street from each other. Emily has been a constant for Hailey since the two have met whether it be supporting each other, laughing with each other, or crying together. Between these two, and their mutual best friendship with Kayla, the three are together all of the time. Emily is originally from Southern Illinois, and moved to Chicagoland after college. Hailey was ecstatic about this, because after living just down the street from each other in college, she could not imagine living hours away from each other and not having readily access to that close of a friend. She is Hailey's built in therapist best friend that has been there through all of the ups and downs, so she obviously had to be standing at her side during the biggest of ups!

Sean and Brennan met at Michiana Raceway Park in South Bend. Sean worked at the track and Brennan would race there most weekends in the summer. Soon, Sean was close with the Dunne and Harrington families and all three have been connected since. Some of their favorite restaurants to visit on race weekends were The Volcano, La Hacienda, or Pizza King which all have too many memories to name that are tied to them. They have made countless memories at the racetrack and continue to do so to this day. When Sean, Brennan, Hailey, and two of her sisters were at an Indy Car race in 2024 the topic of the wedding got brought up prior to the engagement. That is where Sean first heard he would obviously be a groomsman regardless if there was a ring yet or not.

Julija is Hailey's roommate from college, because of that alone she simply knows too much to not be a bridesmaid! The two met through their sorority at ISU, and also quit that same sorority together. As roommates the two were always together, have shared constant stories, and Julija was Hailey's hungover designated driver to Dunkin Donuts on plenty of not so easy mornings after the bars. Julija is one of Brennan's biggest fans, and simply could not wait for him to finally pop the question. Hailey and Julija's text history throughout 2024 is mostly comprised of wedding idea's and guesses as to when he would ask!

Hailey and Vince have been best friends for over a decade. They went to high school together, attended ISU together, and traveled across Europe together. When Hailey and Brennan started dating, Brennan was going through Hailey's instagram and saw her and Vince's photo's together in several different countries. Brennan was convinced Vince was Hailey's ex-boyfriend, but was happy to hear he wasn't and the two quickly became as close as Hailey and Vince already were. Vince and Brennan also share a lot of similar interests like Game of Thrones, Harry Potter, and an old fashion with extra cherries.

Catie and Hailey met in high school through soccer! They grew extremely close through trauma bonding over how terrible their team was, their very interesting coach, and so much more. Their last semester of senior year, they spent almost every day together. The sleepovers were endless! The two even traveled to Disney together after graduation, which was the perfect storm (one of Hailey's favorite people in one of Hailey's favorite places). After graduating Catie joined the Air Force to serve our country. Once that ended, she made her way back to IL, and the two could not be happier to live near each other again! Before Catie moved back, her and her girlfriend Katrina met up with Hailey, Brennan, Brad and Kim. It was that night Catie made it very known that once the question is popped she simply would need to know ASAP, and long behold Catie was the first friend Hailey called to share the exciting news!

Justin and Brennan met while working at Target. They worked in the Meat, Dairy, and Frozen departments together and would find ways to make work entertaining. Justin soon became Brennan’s best friend at work. They had long talks about life, similar interest in sports and music, and loved playing crate basketball in the dairy cooler. Justin likes to claim he saved Brennan’s life when the Target fire alarms went off and Brennan couldn’t hear them in the dairy cooler. Justin ran back to the cooler and grabbed Brennan to “save his life”. It was a false alarm, but Brennan was glad that he had a friend like Justin who had his back. Justin heard about Hailey early on before they were dating and encouraged Brennan to ask her out. Brennan is forever grateful that he listened to Justin’s advice. Justin often comes over to hang and play Mario Kart with Brennan and Hailey, which is always, without fail, within 24 hours of Hailey having a hair appointment.

Logan and Hailey met in college, and he also happens to be dating her best friend/MoH, Kayla. The two couples are very close, and often when they go out to dinner together Brennan will purposefully sit next to Logan instead of Hailey so they can drown out the yapping of the girls with guy talk.

Jaret is Hailey's oldest friend, and the closest thing to a brother to the Bialas family. The two grew up down the street from each other, with mothers that are best friends, and went to every school they attended together from elementary to college.
