When we were kids, some of our parents connected through Facebook, hoping to find others who used the same donor. As the group grew, families began meeting up in real life—starting small with parks and zoos, and eventually planning bigger trips like Disney.

Most of us found each other later through DNA testing sites like Ancestry and 23andMe. A few of us even had the chance to meet our donor, David, before he passed away. Now, the 1223 Sibs is a mix of group chats, reunions, and shared stories—proof that family can form in unexpected ways.
