I am looking for a Mack Family that had a son John born circa 1750 (?) or 1760 (?) Emigrated about 1770 age 10 (?) or 20 (?) Married prior to 1781 or 1791 Mary/Maryann/ Mary Ann or Ann McBride of PA, possibly of Allegheny Co? Does anyone have access to early Ships Passenger lists or Ships Manifests that can do a look up for 1770? Thanks http://community.webtv.net/STARRLIGHT101/COLEMANMILLERGRAHAM
