Cornelius Delamater


Row 11 west side of the northern jut by the parking lot, other stones touching its sides


PRIVATE: Col. Snyder’s 1st Ulster Co. Militia [NYRC+S VI p.188, 259] and under Capt. Van Beuren, Capt. DeWitt, and Capt. Swart [NYR p.357]



He was born October 28th, 1744 and baptized November 4th in Kingston to Abraham Delamater Jr. and Sara Van Gaasbeek. The sponsors of the baptism were his grandparents, Cornelius Delamater and Margriet Steenbergen. He married in Germantown on September 8th, 1767 Rachel Sleght (1748–1835, a daughter of Benjamin Sleght and Anna Swart) and they had children Sarah 1768, Anna 1772 who married Jacob Feller, Thomas 1774, Conrad 1778, Catharina 1781 who married William Tremper, Benjamin 1783, Elizabeth 1786, Effie (Eggjen) 1789 who married Benjamin Van Vredenburg and William (Wilhelmus) 1789 (twins who were baptized at the Germantown Reformed Church), and Margaret 1792. In 1807 when the Rhinebeck Reformed Church was raising funds for a new building, he contributed $5.00. Cornelius and Rachel’s daughter Anna was married in Rhinebeck in 1790. Cornelius died May 7th, 1812. He, his wife Rachel (with whom he shares a gravestone), and sons Conrad and Benjamin are buried in the cemetery.

There are two men named Cornelius Delamater who were young men during the Revolution from Kingston: the one above and his cousin Cornelius born 1760 to his uncle (also Cornelius 1719–1770). The younger man married Sarah Krom and died in 1842. It’s hard to tell who is who in the census of 1790, 1800, and 1810. The younger would have been 23 at the close of the war, the elder, 39.

“Cornelius Delamatter”, “Cornelis C. Delameter”, “Cornelius I. Delimater”, and “Cor’s J. Delamature” are all listed as privates in Col. Snyder’s 1st Ulster County Militia [NYRC+S p.188]. “Cornelius Delamatter Jr.” earned land bounty rights for the 1st Ulster under Capt. Simon Greer and Capt. Cornelius Newkerck [NYRC+S p.259]. and “Corn’s C.” “Corn’s J.”, and “Corn’s” Delamater are listed as serving in the 1st Ulster under Captains Van Buren, DeWitt, and Swart [NYR p.357], so it stands to reason that both these Cornelius Delamaters fought in the Revolution.

Another Cornelius was born 1740 and married Blandina Degraff and baptized at least two children in Rhinebeck, but never had any ties to Ulster County and later removed to Delaware County. It could have been this man who signed the Articles of Association at Northeast Precinct [CHM p.68].
