I recently worked out that Benjamin Douglass married Roby Wheeler in the early 1830's in Jefferson County, NY. Roby was the daughter of Silas Wheeler and Sally Bishop. Silas and Sally married in Chesterfield, NH on 24 Feb 1803. They went to Jefferson County, NY by about 1810. Sally died in 1823, and Silas remarried to Leonora Powell Belding, the widow of Aaron J Belding in 1824. Silas and his family members had gone to WI by the 1840's. Researchers of this family have stated that Silas' daughter Roby had married an unknown Douglass.
Silas was the brother of my ancestor Leonard Wheeler. They are both sons of James Wheeler and Rachel Unknown of Chesterfield, NH. James was born in Greenwich, MA, son of Ephraim Wheeler and Hannah Marks. My Leonard Wheeler also went to WI, in the mid 1840's. He lived in Dodge County, next door to Jefferson County, where I suspected another brother, Ephraim had gone, and died in 1844. While looking for any of Ephraim's children in Jefferson Co. WI, I found that a Benjamin Douglass was there.
There is a Dodge/Jefferson County WI Genealogical Society that has a clipping service that is searchable, so one of the names I searched was Douglass. There were a couple of pedigrees that contained Benjamin Douglass and Sarah Bell Douglass. I just got the information back from the society this week, and the pedigree does show that Sarah Bell is the Daughter of Benjamin Douglass and Roby Wheeler.
A Benjamin Douglass can be found in the 1835 NY census of Jefferson County, in the part of Lyme that later became Cape Vincent. Interestingly, the census shows that the family had a daughter born that year, which would be Sarah Bell. Silas and Leonora Wheeler were also living in Lyme at that time, and appear on the same 1835 census page as Benjamin Douglass.
