Looking for information on the Parents ofPeter DeGroot (abt. 1750- Nov. 1799) and Cornelius DeGroot (March 27, 1754- Dec. 13, 1837). Peter DeGroot married Catherine Halenbeck in Loonenburg, Green, New York in Aug. 18,1782. Their children are Annetje, Catherine, Rachel, Staats, and Madalena and Maria.Cornelius married Maria Van Loon Oct. 28,1782. Their children are Cornelius, Albertus, Maria and Rachel. I believe Peter and Cornelius' father is Staats De Groot who I find one record of in Coeymans in a will and another reference when Cornelius is married.
