Hi Kathleen, many thanks for your response to my ancient (2002!) posting. I was hoping to discover something more about Ruth Sylvan Becher but I think it is entirely possible that her middle name was changed when she was very young assuming that the 'P' in the 1910 Census was correct.
I agree with you, Percy C. Becher does appear to have been married three times. He died 14.11.1960 at Oregon City, OR.
I suppose it may be possible to track down any marriage from local newspapers.
