I am trying to track down the parents and siblings of Jane Conley. She was born and died:

B: 26 Apr 1822
County Of Londonderry, Ireland
D: 22 Aug 1902

She married William Wilson Steen June 23, 1840 in Livingston Co NY at York Center.He was born and died:

B: Mar 1816
County Of Londonderry, Ireland
D: 26 May 1886
