Well hit me, here's my #21:
Margaret Leehive, daughter of John Leehive and Unknown. Born about 1867 in England and died before 1900. She married Martin Slattery around 1884 in Ulster County, New York.
What I also know about Margaret Leehive based on family accounts and backed up by the 1910 Census is that after she died her children were taken care of by her brother Michael Leehive.
