I might be the last living member of birth family and not even know it the last of my kind and I just might be the only living member of birth family

I actually wonder if maybe seeing as I'm adopted maybe I might actually be the last living member of my biological family and the only surviving member of my biological family left today and having no biological family left alive and maybe I'm the last of my biological family only surviving member of birth family today in 2025 maybe i'm the last of my kind
