I am looking for any information on Patrick and Margaret Morrissey who lived in Oil City, PA from about 1864. Both were born in Ireland. I found a marriage certificate for a Patrick Morrisy and Margaret Preston dated 1848 in Newberry VT. Patrick died in 1891 and Margaret died in 1910. She lists Richard Preston and Bridget O'Brien as her parents. I believe they lived in St. Mary's, Perth, Canada around 1861. They had several children, including my great grandfather, Richard who married Mary Ellen Wolford.
