I have been researching MCKEAN family in Westmoreland Co. PA and have recently been led to York Co. Is there anyone on this list researching this family? I have John, Hugh, William, Agnes and Elizabeth MCKEAN on some estate papers in 1750 & 1764 trying to tie this family with the John MCKEAN who died in Westmoreland Co. in 1812. In the History Of York County are there any MCKEAN family listed? Thanks, Carolyn
