My husband's cousin just let us borrow his mother's research on the App Family.Amelia (Emma) App was my husband's great aunt. His grandmother was Matilda Helen (Tillie) App. I have some information about her parents and grandparents if you still want it.
My husband's aunt complied this information in 1972 and 1973. Since I have been verifying the information through Ancestry.com :ie census records and such, I have not gone through all her papers just copied everything. I hope to visit Louisville and do research some day.
