Hi: On further inspection, the 1880 census indicates that Jennie married John G Brown, and that Sarah is listed as Jennie's sister rather than George's sister. John and Jennie had two children. One is named George H, and the other's name is unrecognisable. The handwriting is good but the first name appears to be Bezoe, Rezoe or Refoe. I have copies of the 1870 and 1880 censuses and can email them to you if you contact me directly at
