so far not in the Bengjog Jones family nor the John Griffiths.
but the Jones family has a long history with a Griffith Griffith. i know that could be a possibility there. In the Benglog Jones line we have two brothers m. to two of Griffith Griffiths daughters. i know that one of the families went west to KS and made it big. i am not certain of this man's other children. Ruth Jones is not a name i am familiar with. on any of the lines either. there are Jones in the Griffiths' line as well. I know one last known was in the Denver area with a son. will keep eye out for your lines. do you have dates for these people and have you ckd familysearch.org.
