I am researching the descendants of Molly Brant-Johnson. I am starting from Chester County Pennsylvania and tracing backwards to Helen Martin and Molly Brant-Johnson. My Martin/Johnson ancestors showed up in Southeastern Pennsylvania about 1830. My direct ancestors are Charles Martin and Sarah Johnson Martin (both born about 1810). They were listed as Mulatto, and having been born in Pennsylvania. However, a distant cousin stated that they were Mohawk Indians, and probably connected through John Smoke Johnson. Her direct ancestor is John Wesley Johnson. The connections I am looking for may begin with in the Ohio Valley with Chief Joseph Brant.

I would appreciate any assistance in my search.
