You have more information than I. One of my main lines is the Siders. I have as a source Stephen Richard Anderle. I used his web site http://www.familytreemaker.com/users/a/n/d/Stephen-R-Anderle...
on feb of 2000. I have not visited it in a while and don't know if it has been updated. I don't have John's parents or his place of birth.
I also received an email:
RON HI MY NAME IS JOAN CONKLIN MY GRANDMOTHER WAS EMMA E. MOODISPAUGH HER FATHER WAS JOSEPH MOODISPAUGH WHO PERHAPS IS JOHN AND MARY SIDERS MOODISPAUGH.
At the 1880 Census, John would have been about 64 (if alive) and Joseph could have been 35 ( don't have a date of birth) but it fits. I have Joseph's wife as Ronda Roberts or Chamberland. So the Census may have had her nick name or I'm incorrect??
I know this is probably of little help but I can be reached at email@example.com
