History: Isaac Deforest from Leyden in the Netherlands married Sara Dutrieux in New Amsterdam in New Netherland (now New York City, NY) in 1641. He was of French origin; his father was from Avesnes in Pas-de-Calais, France. Among Isaac's descendants various altered forms of the surname are found, which are in most cases the same as unrelated names of Dutch origin (see Defrees and De Fries ). However, descendants of one of his sons, Philip, also bear a distinctive altered form of the surname, Defreest .
