What became of Mary Bartley?

    Mary Bartley was born in New York City (Manhattan) circa 1846, daughter of David Bartley and Margaret Burnes.  She was a member of the Bartley household when the 1850, 1855, and 1860 censuses of New York City were taken.  No further record of her has been found.  According to the 1860 census, her given name was Mary Jane.¹

    Mary was still alive in 1862 when her father opened an account in the Emigrant Savings Bank in New York City, since he stated he had four children by his "former wife." (Margaret died in November 1860 and David had remarried.)
    Since Mary Bartley was not found in any 1870 census, she was probably dead or married.  She was not buried in either of her father’s plots in Calvary Cemetery, so it is likely it was the latter. 
    Marriage records indexed by the Italian Genealogical Group include Manhattan 1866-1937 and Kings County 1871-1937, and those of the other boroughs from 1898 and later. These records do not include a marriage for Mary Bartley.  Unindexed records have not been searched. 
    The indexed marriage records on FamilySearch reveal many brides and grooms whose mother’s maiden name was Mary Bartley; however, no proof that one of them is the person sought has been found.
