I am looking for any information about my great, great grandmother Mary Gates Briggs. In the 1850 U.S. Census she is living in Dansville, Steuben Co. in upstate New York. She is the second wife of Leonard Briggs (1793-1858). They have two sons Warren b.1843 and Leonard, Jr. b.1849. In the census she gives her age as 26, so her estimated birth year is 1824 and she gives her place of birth as New York. This is all I know. If anyone has any information on Mary Gates please let me know.
