My Kay family emigrated from Germany in 1880s and came to Iowa (Mineola and Minden). Several of them moved to Nebraska (Pender co, Wayne co are the ones I can remember off top of my head). There are many with the same name and those get confused a lot.
If you can give me any specific names, date of birth, etc I should be able to help you. See if you can get grandpa's info and his parents.
look forward to hearing from you
