OK, now you have my attention!
My great great grandmother, Catherine Corey married Andrew Brown in 1874 and my great grandmother was born 5 months later. Family lore has always been that we are part Indian (Cherokee is what one aunt said) and this is the only branch where that could possibly be. Catherine, according to a family Bible, died on Feb 14, 1877. I've looked at all of the Andrew Browns that might be of the right age in that area and the Andrew Brown enumerated with the Pullum/Pellum/ Pulliam family keeps popping up. I was told by an Indian genealogist that many Indians used the surname Brown. I'm not completely sure that Andrew was my great grandmother's father, but he was married to her mother at the time she was born on July 3, 1874. The fact that you say your Olive was Indian definitely has me intrigued. Pulliam is not an easy name to research when they kept changing the spelling, but Brown has been about a nightmare. Maybe only Smith or Jones would be worse. At any rate, will let you know if I find anything more. I want to look into this Pulliam family a little more closely, now. Thanks, Laura Engel
