James, You can look for Cuthbert Harrison's regimental service in F. B. Heitman's _Historical Register pf Officers of Continental Army During the War of the Revolution_ (1893), which generous volunteers have put on line for you, here: http://www.hudsonrivervalley.net/books/historicalregister/ You can find which microfilm roll the regiment's rosters are on in the list here of microfilm in the National Archives' Micropublication #246. The list was most generously compiled by John K. Robertson and Bob McDonald, and posted on their wonderful web site for the common good. http://www.revwar75.com/ob/m246.htm You can borrow the microfilm by inter-library loan, or purchase a copy of the microfilm roll directly from the National Archives. Good hunting, Judy
