Hello. Yes. This is the same Harold Dwelle. The info I have, if all correct is: Amelia Littleton's children-- William & Wilbert (twins) b3-18-1868 Addie (probably your Ada Amelia) b3-10-1875 d4-30-1875
Fannie Christofel's children: Nelson Pearl b 2-5-1880 d1967 Luella b 2-5-1880 d 12-19-1976 Leslie Mort b 1-9-1888 d10-6-1980 Harold b 8-30-1890 d11-9-1987 Amelia b9-13-1893 d8-22-1970 (prob your Emily) Elberta M. b8-10-1895 d2-19-1960 Marguerite b 3-28-1898 d4-22-1974 (Marguerite married an Albert J. Kosbab but I am not aware of any Albert as child of either Amelia or Fannie).
H. Dwelle (married to Lina Christofel) H was for Hubbard. 1850 census shows him as Elijah H., later references all say Hubbard.
I have very little yet on Christofels, but do show both Caroline (Lina) and Fannie as sisters. There were several other siblins too. All children of Adam Cristofel and Elizabeth Meyers (both born in Germany, died in Sandusky). Also, I have seen various spellings. Ohio Veteran's Home records on Hubbard Dwelle list his wife as Caroline Christophel.I connect with the Christofels. Fannie was my Grandmother Mary Edith Dwelle Scott's paternal grandmother through her father Leslie (Les) Dwelle.
