The following are two collateral lines of my ancestor, James THOMSON. Brothers Andrew WATSON, b. 1755, Old Kirkpatrick, Scotland and William WATSON, b. 1761, Dumbarton, Scotland married sisters Margaret THOMSON, b. 1759, Glasgow, Scotland and Barbara THOMSON, b. 1761, Glasgow, Scotland. Andrew and Margaret eventually settled in Allegheny Co., PA, late 1700's, and had ten known children including the following surnames: CUDDY BLACK WYLIE McKINNEY MAGEE PENTLAND as spouses of their children. William and Barbara settled about four miles from Pittsburgh on the Monongahela River, also in the late 1700's. They had five known children with the following connected surnames: THOMSON MYERS FERREE. Would like to hear from anyone connected to any of these families. Regards, Marybeth Corrigall ACMBJC@aol.com
