Hi - sorry, maybe not your Pelsue, but it's an unusual name and I have a Ruth Pelsue, m. Joseph Dean, Wilmington, MA, 23 Mar. 1809. They both d. Woburn, MA. Above, from vital records. Vital records say Jos. m. Ruth Pelsue "of Chelmsford", and it would be c. 1788 based on her death - 25 Jun 1868 @ 80y. 1m. 8d. of bronchitis. I can't find any records there, but it may be a starting place.
