I'm pretty sure. Thad was my great-grandfather's oldest brother and on his obituary(he died in 1991) it was stated that he has a sister-in-law named Louise McRae in Texas. Thad was the only brother my ggrandpa had living in Texas. Maggie Mae may be his daughter, I wouldn't know. My grandmother has forgotten the names of her cousins as she's now up in age and was a child when she last seem them. I will contact my grandmother to get more information. Thanks for your help, I really appreciate it.
