Earl, hope you have more insight into this problem by now.I have done a lot of research into the Heustis family of Dearborn County. About 10 of them moved to Dearborn in 1819. (In fact Rev. B. Plummer was married to Hannah Heustis.)Could this William be Heustis instead?Then I'm at a little bit of a loss as to the identity of this person, but would like to discuss.
