I have found a few bits of information on a Henry and Nicholas Timmerman ( often spelled Simmerman) in Rochester Township, Ulster County. They were both signers of the Articles of Association and there are two records of births to Nicholas Timmerman and Margaret Sax in the Wawarsing Reformed Dutch church records, Jacob, b 20 Oct 1771, bap 8 Nov 1771, and Petrus, bap 14 Aug 1774. The Wawarsing church also has a birth of John Timmerman, bap 9 Mar 1777, father, Henry Timmerman, mother Elizabeth Schultz. And another Wawarsing church record has the birth of Catrina Timmerman, b 27 Dec 1801, father, Hendrick Timmerman, mother Elizabeth Kettle. A Henrick Timmerman (Ancestry.com has Simmerman) can be found in the 1800 Rochester Township census, apparently Nicholas and family had moved to Greene Co. by then. Both spellings, Simmerman and Timmerman, were used in the various records. Does anyone believe they are related to this family or have more information on them.

Thanks, Richard
