Looking into a Mary J St John. According to the federal 1860 census, where she was 34, she was from NY. She married Alexander Carter in Hudson about 1850 or 1851. Inthe 1860 census they had four children; Teresa 9, Caroline 7, William H 4 and Elizabeth A 2. The last I can find on her is the 1880 census, which shows her at age 56 and with two more children by Alexander, Arthur 18 and Blance 16. She died prior to her husband going into the Volunteer Fireman Home, in Hudson NY on April 3 1898. I have nothing on her priorto her marriage to Alexander,m any info or assistance would be greatly appreciated.
