There is a marriage record John Sullivan marries Johanna Haly Feb 19 1867.
But John Sullivan and Johanna had there children in Pennsylvania 1855 too 1865,
By 1875 New York Census living in Broome ,New York,same children, also a
Mary Haly staying with them,sister in law.So Johanna is Johanna Haly.John and
Johanna stayed in Cork Ireland and had children in 1868,1870, 1872,So wrong
family.I have seen marriages before with people same names,but only a few.
