I think everybody has hit that brick wall. Though I the Familysearch site had a John Henry Parks and Elizabeth Bigsby as parents, i have no idea where this info came from, and whether it has any accuracy. Censuses have Ephraim and Charlotte as methodists. The Parks identify themselves as Irish and the Spanks as dutch or Scottish. A couple of her grandparents were loyalists from america. See history of methodism and the german/irish immigrant in NY.
