To David M. COFF - David, have you tried getting birth, death or marriage records to trace your grandfather back - there are some good sites on the internet for USA families, including census and Social Security records. I have found a good many COFF names and addresses on the net through a White pages directory - so if you're interested in tracking down your relatives in the USA there are quite a few COFF persons to contact that may give you a lead. Would you like to contact me ?
smaiden@amitar.com.au I'd like to help you in your search as I have done a fairly comprehensive COFF tree for our lot in Australia. Regards, Sandra
