Byron, Thanks for your data. Your info is about as concise and thorough as I've seen in explaining the family descendancies.It certainly helps clarify some of the census data regarding John. It didn't seem that he could be the John on the early records of Pownal and was dubious of him being the John in Clarendon, VT on the 1790 census as he was first carried on the rolls of the Ft Edward militia as Surgeons mate in 1792 and later as surgeon(1798). "The Ft. Edward Book" by Robert Bascomb credits Dr John & his future wifes Uncle, Zina Hitchcock among the founders of the first Masonic Temple in the region. The same source lists him as a surgeon with the Charlotte Co Militia during the Revolution. Dr. John is recorded in Nov 1803 with a land Purchase in Kingsbury, NY with his wifes father, Isaac Hitchcock. The 1790 census records did not carry any Perigo/Perrigo families in Washington/Charlotte Co NY but did Have a Robert and Joseph Perigo Jr. in Albany Co Stephentown, NY with a Rufus listed in Half Moon, NY and in 1800 that reversed itself with two Roberts and a Joseph H Perrigo in Argyle NY and one Robert in Kingsbury NY. John's brothers(David, Branscom, Elijah) meanwhile listed in VT during that period. I did come across the name of a Stephen Perrigo listed along with a James on early tax records in Pownal, VT. but not sure where he fits in. Thanks again for taking the time to share your research. If I can be of any help to you please do not hesitate to contact me.
