I have several Revolutionary War ancestors. I have previously blogged about 4th great grandfather, John Gorin (my DAR patriot), 4th great grandfather, Noah Davenport and 5th great grandfather, John Willet.
Another 4th great grandfather who served in the Revolution is Martin Adsit.
The NSDAR (National Society Daughters of the American Revolution) Genealogical Research System Ancestor Search summarizes Martin Adsit's service as:
Service Source: Roberts, NY in the Rev, p 70
Service Description: 1) Col Wessenfield [sic: should read Weissenfels]
New York in the Revolution as Colony and State can be found at Google Books with Martin Adsit listed as an enlisted man in "The Levies" under Colonel Frederick Weissenfels (page 54). (Col. Weissenfels has an article at Wikipedia.) The Weissenfels' Regiment of Levies (1781–82) was a militia unit from New York which fought in support of the American cause.
At Ancestry.com, there is an index for the Muster and Pay Rolls of the War of the Revolution, 1775-1783 indicating that Martin Adsit, serving under [Frederick] Wissenfells, was listed as a patient in the General Hospital at Albany between October 31, 1781 and November 7, 1781, with a fever.
I have not been able to determine if Martin participated in any battles. It appears that "Levies" were a group of soldiers selected from the ranks of the militia for additional training. These troops were then used to fill in the ranks of regular troops or as independent units. Often Levies served in the forts along the frontier counties in New York in order to stop raids carried out by Indian forces and Loyalists led by British officers.
