This is such a puzzle! I'll give your mother a call this evening after I return from church. By the way, my ggrandmother was definitely mulatto, as was Anna, Clara, and Walter. I have a picture of Irena.

I checked the map for Bell County -- it's not that far from Bowie County -- where I found Walter, and Marion County -- where the Tazwell family lived for at least 10 years. Let stop before I make us long lost cousins. I look forward to exchanging information with your mother.
