A Henry Finn shows up in a property record as owning land in Salem near a John Williams who sold to David Thomas on 12/25/1789. Another Henry Finn, probably his son, appears in an 1845 petition to the Surrogate Court in Jefferson County, reading as follows: Surrogate's Court, Box F-11 Finn
Estate of Henry Finn. Petition of Anne (Anna?) Thomas of the town of Henderson, July 1845. "The deceased was an enlisted soldier of the last war; died in the town of Canandaigua, in the county of Ontario, sometime during the years 1815 or 1816 without leaving any last will ......and there be left him surviving as his heirs at law and next of kin, the following named persons- George Finn of the town of Ellisburgh, Harriet Boomer, wife of Collins Boomer, and this deponent of the same place, William R.

There was also a William Finn in the county in the late 1700's. I am trying to determine the origins on Henry and William.
