Joseph Vance (1613)

"'Vance' as a last name appears to be primarily Protestant Irish in origin although its first use in Ireland is probably from two charters near Galway in the 1580s so it predates the Plantation by about a generation.

"In the Plantation of Ireland starting in about 1604, two known junior sons of the Vans of Barnbarroch, Patrick Vans "of Lybrack" and John Vans "of Longcastle" were planters receiving land down around Donegal town in southwestern Donegal county, although they sold their lands within a few years and there is no real evidence that they spent any significant time there. There was also another offshoot of the Barnbarroch line, John Vaus "of Capenach" who did settle in the same general area in the early 1600s though. Also around 1611 a Church of Ireland minister named John Vans/Vauss/Vance became rector of Kilmacrenan and Movagh in central Donegal and died there in 1665. There was also a Gilbert Vance who was hanged by a mob in that same general area in the 1641 uprising, and a man named George Vance who settled in Tyrone from northern England around 1637. None of these last three Vances have reliable ties to the Vans of Barnbarroch. There are also three Vans/Vances among the 1649 Officer's list who were Royalists who received land in Ireland after the fall of Cromwell, though we don't know if they recieved land around Derry specifically. But the point is just that there were many Vances running around especially in Ulster in the mid-1600s that do not appear to share an immediate common connection."

There's much more, but this should be sufficient to make the point the Vances in Ireland are not known to have a common origin. The DNA results tabluated by the Vance DNA Project bear out the diverse origins of the name Vance, both generally and in Ireland specifically.
