am researching these same lines. My line I am researching is Daniel Carroll b. 1760-1770 Md. and his son Nicholas Carroll b. 1797 MD married Nancy Lord in 1822 Ross County, OH. Handed down history is they are related to the famous signer Carroll's. I believe Charles Carroll who married Susannah Lord and Daniel Carroll are probably brothers. Perhaps Samuel Carroll who married Lovey Lord 1801 MD is kin also. Will share info.
