After many mentions in New York state newspapers (found on the Genealogy Bank website), which I transcribed below, I lose track of Paul's whereabouts in 1820 until he dies and his will is proved in Hudson NY in 1829. I have a theory (unproved) as to where he was from about 1821 - 1829. I'll write about that another day after some more investigating.
Part of the irony of all these newspaper articles is how so little is written about the women at that same time. There is no mention of his wife Lucy Gifford Dakin, not for her death (1821), not even in the articles mentioning the marriage of their daughter Lydia (1810) or in the death of their baby (1805). Another piece of irony, for a man who held local political office and ran a blacksmith business for years, there is no mention of his death in the newspapers.
Take a look through the following articles and advertisements. They not only track Paul Dakin but they give a flavor of life in Hudson NY in the early 1800s -- including newspaper reporting on elections that is very partisan and descriptions of 4th of July celebrations and all of the toasts offered.
