There's no marriages for Dunlop's married in Madison Co from 1810 to 1900 according to the marriage book in the Genealogy Dept in London. And there's no Robert or Peter in any of the 3 census.You must remember that Lily Chapel is about a mile from the Franklin Co. line east of them.I checked their research cards, and no one is listed as researching them in the county.I don't know if this will help much, neither one of them was listed as having a middle initial.
