Shucks, Wendy, thought you'd end up being a cousin! Sounds like you have made progress, so that is most excellent.
And Sandra, as I stated in my post yesterday, Margaret and Charles were married in Butte, Montana on 11/17/1894. Not quite sure where you are getting your calculations from, I show Margaret born in 1853, and Edward being born in 1883, a difference of 30 years. Charles is Edward's stepfather, not his father.
Death certificate shows Margaret's death in 1924. Though I don't have Charles death certificate, articles in the newspaper at the Library of Congress show his death in the mine in Bisbee in 1908.
Hope that helps clear up the confusion
