Extremely unusual
Both sisters were aware of the possibility of having quaternary twins, a phenomenon that is extremely unusual. That’s why we wanted to have overlapping pregnancies,” Briana said. As a group, we all agreed that doing so would be awesome. In all of human history, just 300 quaternary marriages have been documented.
It came as a shock that their strategy had been successful.
The couples opened up to Entertainment Tonight about their unconventional relationship setup in April of 2021. They had planned to get pregnant together, but Brittany and Briana were still shocked when it really happened. Neither one of us knew that we were going to get pregnant so soon after our wedding,” Briana said.
