I am very interested in finding any unknown relatives. i thought i had the only family with this name. thank you for all your helpful information. I have some information you might be interested in. My great grandparents are originally from minsk russia (i hope i spelled it right) and escaped to america during one of the wars, im not sure which one but they had a longer last name and had it shortened not long after they moved here. My gradfather Robert Frank Koff was born sometime in 1916 in New York. And on June 13,1956 My father Frederick Scott Koff was born to robert and Audrey(maiden name: crawford) Koff (married name). I hope this is some useful information and i hope you will post a follow up and tell me if it was any use to you.
