Best Answer - Chosen by Asker: Your next step is to document those people's births, marriages and deaths. The documents will provide information on the next earlier generations to work with.

You may be able to "jump the gun" searching the surname and places(s) message boards at ancestry.com, rootsweb.com, genforum.com if anyone else is researching the same or related families.
