As a follow up on this inquiry, tonight I finally discovered what happened to E. E. Crandall. Thanks to the Library of Congress "Chronicling America" project, the newspaper "The Elk County Advocate" was put online and I found a death notice for him in the paper published on 10/29/1874 that said he died in Baltimore. This is where his daughter Inez (Crandall) Brumble and her family were living. I also found a mention in the 6/11/1874 edition that he went to live with his son-in-law in Connelsville. This is about the time that his son-in-law was in that area, and just prior to them moving to Baltimore. Mystery solved. Now if I can figure out where Malona and Isabella went.
