The 1850 Federal Census is one of the few places I’ve found a reference to my 4th great-grandmother Elizabeth Ambrose nee Leary. She is married to David Ambrose and they have three young daughters: Mary Ann, Ellen and Catherine. They lived in the Western District of the 1st Ward of New York, which is the tip of Manhattan in the area now part of the Wall Street/Financial District. Elizabeth and David were listed as the same age in 1850: 26 years old, which would put their dates of birth circa 1824. Both of their birthplaces are listed as Ireland, while their daughters’ are all listed as New York, which means they immigrated sometime between 1824 and 1847 when Mary Ann was born. Mary Ann is listed as 3 years old, Ellen as 1 year old, and Catherine as 2 months old. David is listed as working as a laborer.
