4a.  Ohio 1910 Census Miracode Index (online at Ancestry.com):  I could not find William or Catharine under any conceivable search parameters.  I eventually found them only by doing a page-by-page search for 861 Wilson St., where they lived in the 1900 and 1920 censuses — thankfully, they stayed put!  In this 1910 record (see next source) there was a Freda JONES living with them.  Oddly, I could find Freda with a search, and even more oddly, she is listed as "living alone" and "head of household."  Go figure…

Catharine's sister, Lucinda, married a JONES.  I wish I could read her relationship clearly.  It could just as easily say, "None," and "Niece."
