Christopher Masters/Meschter IN (b.1778)

I am a descendant of Margaret Masters (b1821 in PA).There is a strong possiblitiy that she is a daughter of Christopher Masters/Meschter.She married William Nelson.They resided in the same town and county in Indiana as Christopher.Can anyone give me information confirming this.I also am interested in knowing all of Christophers other children.The 1850 Fairfield, Franklin, IN also showed a Samuel Masters (1813) living with him, A William Masters living very close by and also an Aaron and another Christopher.All in very close age range, all born in PA and very possibly Christopher's sons.Can anyone help me? -- debbie
