Four brothers, sons of John Turnbull (Sons of John Turnbull and Elizabeth Hamilton and grandsons of Thomas Turnbull and Charlotte Brady):
John Williamson Turnbull
William G Turnbull
James Donely Turnbull
Stillman Lippencott Turnbull
Two settled in Western PA James Donely and John)and two went to Mass (William and Stillman). I know a lot about James Donely because he is my great-grandfather but I don't know much about the other three, esp the two who settled in Mass.
There were also three sisters: Mary, Annie & Elizabeth. I do not know anything about the sisters.
