I have emailed you privately with information, but for the benefit of other researchers to this line, your "Jennie Roper and S. Roper" would appear to be Sarah J. "Jennie" ABBOTT (b. 1854) and Schuyler (or Schouler) ROPER (m. 1873). Please also see my post of February 27, 2000 to the Fillmore queries board titled "Jennie ABBOTT". I have quite a bit of information on the Abbott side and some on the Ropers.
My Grandmother was the niece of Jennie Abbott and was adopted by the niece of Schuyler Roper after her parents died in 1890.
