We appreciate your follow-up. My wife just received her original birth certificate from the Kansas records bureau on Monday of this week, so what little we know is from the few things included on the birth certificate and what we have found doing an internet search. One helpful source of information was an obituary in the Topeka newspaper for a "Shirley Lovelady Hundertfund Cameron" - daughter of Louis and Ethel. It gives the names of 7 brothers and 4 sisters. I don't know if your father's name is listed there. Obviously, my wife's isn't. Don't know if you have come across this, but it should come-up in a Google search of "Louis and Ethel Lovelady."
You mentioned that Sylvia Lovelady has been a helpful source of information. How have you been in contact with her and do you think she would be open to contact from "another member of the family?"
