Sure, any info would be welcome. I know all about Aunt Bernadine. My mom and grandmother (grandma is also named Bernadine) always talks about how she was one of the meanest of the sisters lol. I think they said their favorite aunt was Aunt Maggie, and that the rest were all mean and lived longer haha. I never met Aunt Bernadine personally, so I cannot say for sure if that was true or not.
I am a descendant through Alma Kinney (who married Cecil Buseman), and I am also having trouble finding anything at all on the Busemans. I heard the Kinneys came from Ireland, but I have not been able to get evidence on that yet. Thomas P. Kinney is as far as I was able to get.
I know Aunt Bernadine died back in 2004 and that she is buried in West Virginia National Cemetary in Pruntytown (she was a nurse and served in the Battle of the Bulge in France.) I do not know if she talked about her parents at all, but the Abernathy name is also one I am searching for. Her mother's name was Katia and I think she lived in front of a family cemetary in WV. I hope some of my info might help in some of your searches.
