The direct line of the Stoy family goes back only five generations to Philip Stoy of New Jersey. Other family lines go back much further and a simple way to see the known families is to take a look at the two pedigree charts, one for Robert Stoy and one for Mary Louise Young. It's clear that there are still many unknown ancestors, some in relatively recent generations. Others remain unexplored in their native countries - the Fleming and Morrison families are examples (one came from Scotland and the other from Ireland) and there is not yet enough information to trace these common surnames.
