I working on the Michigan Van Deusen/Dusen/Duser/Duzer, etc group trying to break a stone wall. I've been putting together a database of the early members, (1790, 1800) and Michigan to 1850. I ran across Griswold, "Major Griswold" is the reference in the Kalamazoo County History, and if he were born in 1808 then perhaps it was a joke. He came here with his brother, Alonzo round about 1828. Later another relative, Alanson, joined them. The two brothers ran a sawmill in the mid 1830's in Prairie Ronde Township. Griswold disappeared before the census. Alonzo stayed in Michigan (Watch out for spelling. He was listed as Alonzo Vandarson in his marriage record in 1835. He appears to be buried in Harrison Cemetery in Kalamazoo Co, MI and if I'm interpreting the photograph correctly, he died in 1845, age 44 yrs. There is a Jacob Vanduzer in LeClair City, in Scott Co, born about 1811. That makes him the right age to be another sibling in this family especially since Griswold came with a J M Vanduzer.
I suspect the family originates from southern NY, simply because of the 'r' ending on the name which is found in Orange Co. However the Great Barrington Van Deusens of MA also used Alonzo and Alanson as family names. I was unable to connect them with any of the family in Alfred Harrison Van Deusen's Genealogy. If they were still following Dutch custom, then the father may have been named Martin.
