Trying to find information on Mary J St John, she was born in New York about 1828 and died in Hudson New York ca 1900. The earliest I have been able to locate on her is the federal 1850 census., That shows her and a sister, Caroline L St John, living in ward 10 of New York city. They appear to be sharing a house with two families. Those were named White and Huger. The census lists Mary as 22 and her sister as being 18. Mary went on to masrry a Alexabder Carter in Hudson New York. They had several children, all whiule living in Hudson. Any assistance or information on her early luife would be greatly appreciated.
