We know Stephen teaches in Southold, NY in the early 1870s. It seems he was there when his wife was pregnant which gives more credence to the idea that she was living with her mother in Brockport during that time. I wonder if he was there when she died? When his son was born? In the article below, Stephen's return to Binghamton is noted in December 1873. Jennie died in March 1873.
