Oh, the family history you do know is so lovely & romantic (and definitely should be a book someday)! The ancestor I know the most about is my Polish great-grandmother, and even that is somewhat sketchy.
All I know about my Welsh roots is something about an Abraham Jobe (the 'e' was added later, though) who came over in the mid-1600s and worked, I believe, for William Penn. I like to imagine, given the OED definition of Jobe (“to rebuke, reprove, or reprimand, in a long and tedious harangue; to ‘lecture’”), that Abraham was a grammar stickler, which was how he got the surname in the first place, but I suppose it's more likely that the source was related to religious beliefs, given the later connection to Penn.
