I don't claim to be an expert but if you haven't done so already get the book "History and Antiquities of the Name of the Family Kilbourn" written by a Kilbourn (believe the first name is Peyton) There is a wonderful long account of Aaron Kilbourn's life, written by him. It is available on the genealogy.com library. ALso, if I remember correctly, Lucinda married a Fairchild and is in the Fairchild genealogy also at that site.
I am descended from Lucinda's sister Patience Kilbourn who married John Reynolds.
Since we are tracing the same lines, would be happy to share what I have.
