Dear Chris: Thanks for writing back. I hadn't really given much thought of Catherine dying when she gave birth or shortly thereafter Adeline's birth--am going to order her birth and death records from Edwards Co. Adeline died in 1888. That's probably why she wasn't mentioned in the estate papers, etc.
Adeline had a half sister Catherine Harper Tait.I am surprised she hadn't lived with her as Catherine was about 17 when Adeline was born, but who knows as most of them were probably illiterate we will probably never know.
Thanks for the info and thoughts on Catherine and Adeline. You have been a great big help! Have a great week!!
