I am trying to find any info on a Cassidy family that might have been living in Westchester county NY around 1850.
Edward Cassidy b. Ireland 1800? married to Mary Halpin b. Ireland 1810??. Family came to the US around 1842. They had a daughter, Margaret Mary Cassidy b. 1836, Ireland. Around 1851, Margaret married a Thomas Conaty. They were living in Ossining in 1860. Their daughter Eliza was born 1852.
Looking for any clues or leads to this family..
thanks in advance..
