Jerusha (Backus) Osborne was my Laura (Backus) Richmond's sister. The 1880 NY Census in Livonia, Livingston County, New York, has Jerusha, age 60, as a "confirmed invalid" with paralysis and marked as "Insane." Enumerated in between Jerusha and her husband, Henry Osborne, was Catharine Whaley, age 32. Her relationship with Henry Osborne is "Mistress." MISTRESS!!! Catharine was the mother of Henry's sons, Willie, Charles and Myron.
In 1870 Catharine Whaley and two year old son Willie were living in the Osborne household. In 1870 Jerusha was listed as "housekeeper," apparently not paralyzed, but perhaps playing second fiddle to Catharine, she was on the road to insanity? Henry Osborne's 84 year old mother, Polly, was also in the household. Interesting times, no doubt.
