Briana and Brittany Deane hated each others' boyfriends as teenagers. "So often, we were in relationships with singletons who didn't understand our twin sister bond," Briana, one half of the identical twin sisters pair, told Insider. Deep down, the sisters nurtured a shared dream of marrying a set of identical twin brothers. "I think there was some underlying stress that if one of us got too serious with a singleton guy, then it would ruin this dream we had, which was always our hope, even though others told us it was unrealistic," Brittany said. So when Briana and Brittany met identical twins Josh and Jeremy Salyers at the 2017 Twins Days Festival in Twinsburg, Ohio, they knew they'd found something special.


Exactly a year later, the sisters' dream came true. The couples—Brittany with Josh and Briana with Jeremy—married in a joint ceremony at the Twins Days Festival in 2018. Now, the couples live under one roof in Virginia and run a wedding venue site together. "It was something we all four wanted and when we got engaged, we all wanted it that way," Brittany told TODAY of their unconventional living arrangement. "It’s something that's very nice. (Josh and Jeremy) understand the twin bond like we do. We get to have a lot of together time."


Aside from sharing the same last name, house, and business, the couples also share the responsibilities of raising their babies, who are so genetically similar that the cousins are more like brothers. "You've heard the term Irish twins and you've heard identical twins and fraternal twins," said Briana. "But we have quaternary twins. They were born to identical twin parents less than nine months apart. Twins married to twins who both have babies at the same time." The Salyers are parents to Jett—who turned 1 in January—and Jax, who will turn a year old in April.


Since identical twins share the same DNA, the children of two pairs of identical twins are genetically similar to siblings even though legally they are cousins. Briana and Brittany revealed that they had both discussed the possibility of quaternary twins. "We were hoping that we would have overlapping pregnancies so that this would happen. We thought it would be really cool," Briana said. "There's only 300 quaternary marriages known in the history of the world."


Speaking of co-parenting the boys, Jeremy previously told Entertainment Tonight: "I feel like I'm Jett's parent and I think [my brother] feels the same way about Jax. We all live together and we are raising the kids together. It feels like one family unit, not two separate couples with their own babies. It's the four of us with our two babies." The couples are still working out what their children will call each of them and are currently considering ideas like "daddy" and "duncle," and "mom" and "aunt mom." They admitted that sharing glimpses of their life online does expose them to negativity.


"We try to ignore sociopathic stalker comments and just focus on the positive," Brittany said. "Some people think we are really strange and others think it's really amazing. We've gotten a lot of support and interest and we've been grateful for that." As for the possibility of more babies, the couples are still undecided. "We are debating if we should go for one more pregnancy each or not," Briana said. "We will make a decision pretty soon. The babies are still pretty young (and) we are trying to wait a little longer to see what to do."
