Hi; I find that Emerine Nidey, wife of William, died 25 JUL 1879.
www.findagrave.com lists her as well as her daughter in the Martin-Carr Cemetery. I'll see if I can find anything after work today. Rather confusing if Emerine "took care of the Gates children" after their mother, Angeline died in 1883. We'll figure it out. Please feel free to email me directly at email@example.com Thanks, Bob
