I have come across two obituaries in newspapers from the state of New York for people who were originally from Paulstown.
The first is for what looks like the name of Michael Fenelon. The page of the newspaper is very worn. He died on 1 September 1891 in Brooklyn, New York City. His parents were James and Catherine Fenelon. He was about 56 years of age when he died and was buried in Holy Cross Cemetery, Brooklyn. An address of his last place of residence is given. Again, the page is quite worn here but it looks like 83 Amity St, which is in Brooklyn.
The second is for Catherine O’Haire who died on 3 May 1931 at the age of 92 in the town of Niagara, NY. She was born in the parish of Paulstown about 1839 and came to the United States in 1863. Her husband was John O’Haire and the obituary says that he died 33 years previously. They had two daughters and three sons and she was buried in Riverdale Cemetery.
