On June 28, 1849 The Guy Mannering ship landed in New York, having come from Liverpool with some of my JACKSON ancestors. Dennis 40; his son Dennis 10; Johanna 35; Kate 8; Ellen 6; John 4; and Mary 1. Living in the same New York City household with them when the 1850 Census was taken was Mary COGHLAN who seems to be the same person who had moved to Chicago with little Mary JACKSON by the time the 1860 Census was taken. Little Mary was living with an older Mary JACKSON at the time. The older Mary JACKSON was my great-great grandmother, and the younger one was my great-grandmother whose obituary shows that her dad was Dennis JACKSON. Younger Mary and her parents had lived near Belfast, Ireland prior to coming to the United States. Does anyone else on this list have a connection to my JACKSONs? Thank you.
