Update (2023-06-03)—Margretha’s origins have been discovered! I’ll put a link to the solution to this mystery at the end of this post.
There are brick walls (ancestors whose own ancestry resists all attempts at discovery) who will probably always be brick walls. These individuals often lived in times and places where record-keeping was sparse or non-existent, or were trying to run away from their past or reinvent themselves, or had descendants who purposefully or accidentally destroyed evidence of the ancestor’s life, or had other circumstances that make it understandable why we may never learn about their ancestry.
And then there are brick walls who have no reason being brick walls. These individuals lived lives that were relatively well documented, they were not trying to hide their past, they had/have descendants who cherish their memories, and they’re only a couple/few generations removed from living descendants. My third-great-grandmother Margretha (“Marg”, “Maggie”) Gores is just such a brick wall. She’s one of my most enduring brick walls and she’s certainly the closest to me in time. For my Prettyman cousins reading this, Margretha was Judge F.E. Gores’ mother.
