My cousins and I are seeking first name of Mr. HENDERSON who possibly married 1st) Lucy LEONARD b. between 1816 & 1823 in Oneida Co. or Oswego, Co. NY, daughter of Benoni LEONARD & Mary or Lucy BROOKINS, BROOKINGS or BROOKENS. Did they have any children?
Mrs. Lucy LEONARD HENDERSON may have married Ira KENYON or KINYON (possibly her 2nd marriage) and had sons: ~Frederick L. KENYON b. 1844 NY, d. 1914, and ~Frank KENYON b. ca 1847.
Thanks to RRK for this data as well as the 1860 Mexico, Oswego Co., NY, census lookup.
