My g-g-grandparents, Philip (21) and Bridget (19)were married October 10, 1841, and immigrated to the USA on the ship "Perseverance", arriving in New York May 11, 1842. They were traveling with another couple, Michael Clark(27), Biddy (32), and their three children, Matthew (10), Anne (8), and Margaret (6). Philip and Bridget eventually settled in Chicago, Illinois. Family tradition has the Clarks being from County Cavan. We would greatly appreciate any help locating their families, place of birth, marriage, or any other details.
