FISK, FISKE, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male FISK (or variant) can participate in the Y project. It's always a big help to other project members and researchers to include your earlier known ancestor (EKA) in your profile. We're also happy to accept Family Finder and mtDNA testers. Please understand, however, that FF and mtDNA results will generally yield no clues about your early Fisk ancestry.
