I am researching this line. My great great grandmother was Marcia Deuel, 6th child of Joseph Putney Deuel and Melinda Cody.
Have you found any additional information since this post? I actually have quite a bit of information on Benjamin Deuel (father of Joseph Putney) provided to me by my grandmother. He was born Jan. 6 1764 in Washington, Dutchess County, NY and died Feb. 20, 1846 Aurelius, Cuyuga Co., NY. He was first married to Sybil Putney (it is believed that her father was a Joseph Putney). This marriage occured prior to 1800, but it is not known when she died. He did re-marry to Hannah Birch in Oct. 1822 and there were no children from the second marriage.
There is little, if any, information about Sybil Putney. If you have uncovered anything, I'd love to know. I am happy to give you more information about them, if you still need it.
