Once you have a proper Regiment designation you can:
1) Look for a Compiled Service Record on www.footnote.com or www.ancestry.com
2) Look for service record in Revolutionary War Rolls, National Archives Micropublication #246.The Microfilm Roll Numbers' contents are listed on this dandy web site: http://www.revwar75.com/ob/m246.htmhttp://www.revwar75.com/ob/m246.htm
--these rosters listed in #2 are what the Compiled Service Records in #1 were extracted from.
Once you have the microfilm number, you can browse through images of the rosters on the appropriate microfilm roll on ancestry.com, or ask your library to borrow the microfilm roll(s), for you to look at (at the library) through inter-library loan, from the National Archives.Libraries generally charge a few dollars per microfilm roll for this service.
Your local library may also subscribe to ancestry.com or footnote.com for patron use at the library.Each of these database-source sites has free trial periods as well.
Your genealogical questions are best posted on surname message board or message boards for Counties of residence, since they are not about the Revolutionary War.
