Your 1999 posting is an old one, but of interest to me. I have no idea what information was sent to you by others responding, but wanted to ask you if you could send me information concerning your generation,i.e. brothers, sisters, their marriages, etc.
If you still need any specific information concerning your grandparents generation, let me know and I will send everything I have.
I have developed a Hartline family tree beginning with Nicholas and Barbara in Weigenheim in abt. 1660 up through the present day. It isn't finished yet.
