My tree shows an Imogene Gaby born in 1864 to David Gaby and his wife Ann. I do not have a maiden name for Ann. David Gaby is generation 3 (George W.2, George W.1) David Gaby was born December 12, 1825 in OH.
Perhaps Emma Jane & Imogene are the same person? The names sure sound alike!
She had three siblings...Mary Ann b. 1859, Lewellyn b. 1867, and Josephine b. 1869.
