The Snively family arrived in "the colonies" in 1714, they eventually settled in Antrim Twp PA in 1731. My 6th gr grand father (Jacob Snively 1695-1766), however, appears to have had 21!!! children with 2 wives between 1720 and 1765. I haven't traced most of their families. :P So, best guess, someplace around Antrim PA.

Possible, or Reason could be a nephew or cousin as well, who was coming "out west" to try his luck but wanted to be near family.
