Madness Monday -- Where was Ida Dewey?

A couple months ago, I posted a Madness Monday about Samuel Rhoades/Rhodes, who is driving me nuts because I cannot find him anywhere! He isn't in censuses, except for one possibility. I haven't found a marriage record or death record. He's definitely a man of mystery. His wife is not as mysterious, but I'm having a hard time finding her, too.

The best mention I have of Samuel is in his son Andrew Lewis Rhodes's Railroad Retirement papers. Andrew states that his parents were Samuel Rhoades (spelled that way; Andrew spelled it Rhodes, and that's the way we spell it today) and Ida Mae Dewey. Andrew indicated with a question mark that he did not know his father's middle initial. That was on a form dated 19 November 1938. On a later form, from 1952, Andrew gave his father's name as Samuel H. Rhodes (without the "a"). The individual I found on the 1870 census is Samuel H. Rhoades, with his family in Ohio, in the same town where the family of Ida Mae Dewey lived. This is the strongest possibility.

But between that 1870 census and the 1900 census in which she is the wife of Andrew Shuster, with her younger son Harley in the house, I cannot find Ida Dewey. So the search continues, as does the madness. I hope someday to travel to Ohio (I have family history research to do in Illinois and Indiana, too) and clear up this mystery once and for all.
