I have a copy of Frederick's pension. It states that while he was residing in New Brunswick, NJ, he enlisted in the summer of 1776 and served 2 months as a Private in Captain John Taylor's Company of Colonel Duyckin's (also spelled Duychinck) New Jersey Regiment; from sometime in the summer of 1776 to about June 1, 1777, he served at various times on short tours, as a Private in Captain Lawrence Van Cleef's Company, Colonel Henry Vandyke's New Jersey Regiment.
About June 1, 1777 he enlisted in a company of light horse commanded by Captain John Stryker, New Jersey troops. He was not engaged all the time in active service but kept himself in constant readiness to mount and ride for an over all period of about 7 months.
August 1, 1779 he was appointed forage master under Sidney Berry, Deputy Quartermaster General; this service he rendered at different times until the close of the war for at least one year in all. Frederick participated in the Battles of Monmouth and of Springfield, as well as in a number of skirmishes. He was allowed a pension of $30.00 a year by application executed on September 25, 1832 under the Act of June 7, 1832, at which time he was 79 years old and lived in Scipio, Cayuga County, NY.
Frederick died June 20, 1835. Many of his descendants remain in Scipio and nearby towns to this day.
