While searching records last week I printed out the will of Thomas McKee, Fayette Twp., Allegheny Co., PA written 20 May 1803. It was probated in Beaver Co. PA 13 Jun 1807 is listed in Beaver Co. Will Book A, p. 15 and can be found on FHL US/CAN Film . This is not my line but he mentions so many heirs by name that I thought I would share.
Heirs mentioned: Mother, Mary McKEE, Father deceased.
Brothers' and Sisters' children: James McCAUSLAND, Thomas SPEEDY, James PEOPLES, Thomas LUSK.
Brothers: William, James and Andrew McKEE
Sisters: Martha WILSON, Ann DICKEY, Mary SPEEDY, Isabella LUSK, Elizabeth PEOPLES.
Executor: Edward PEOPLES and another illegible of Mahoning Co.
Witnesses who swore to having seen Thomas McKee sign the will were James WALKER and John LUSK.
Hopefully this might help someone else trace a line of family. Nancy Smith
