I don't know this particular Jones family, but I wanted to make a point: Just because someone is listed as a widow doesn't make it true. My great grandparents lived a few blocks from each other in 1910 and she was "divorced" while he was "widowed". Somewhat different in the next census. I don't believe they ever were divorced, since they were again living together when he died in 1955. I knew them at that time. People aren't always truthful when giving information.
