I am also descended from the Dill's of Delaware. My pedigree is at

I am most interested in your DNA evidence. I have been trying to get more Dill descendants to submit Y-DNA in hopes that we can discover links to our common ancestors. So far we have myself and John A Dill and Bob Dill (of Denver) who are Delaware Dill descendants; Larry Dill of the Caleb Dill-New York line; and Robert Dill of the Nova Scotia line. Our DNA is listed on the Family Tree DNA site (Ysearch) with the Dillard (et al.) group.

John and I match and define a Dill Lineage I.
Robert (NS) and Larry (NY) match and define Dill lineage II.

It would be interesting to know how your DNA matches.
