Since you don't give a name, I can only suggest doing a web search for the term and do a search in the MD Archives volumes on Revolutionary War records:http://www.msa.md.gov/megafile/msa/speccol/sc2900/sc2908/htm...

-- you must register and get a password to use the site. These sources are genealogical, not about the Revolutionary War, and further inquiries about the individual should be on the surname or the County message boards.
