Betty,
What an interesting family history you have! Thanks for telling me about it. I've actually found the information I needed on Emma Kate Corkhill. It was right under my nose in the library at which I work. Turns out she was an English professor here at Simpson College about the turn of the century. Obviously her books came to us after her death because she had worked here.
I really hope you can find some information about your family history. I have mine traced back to the 1400s in Scotland. It's so refreshing to know where one has come from. It's only then that we truly know where we're going. Good luck with your search. :)
