A relatively (no pun intended) unspectacular name, but my husband's grandmother's surname was Mandall-Hall. Given that they were all farm labourers, I was very puzzled as to how they came by a double-barrelled surname. Had to go quite a way back to find out how, and also found that they were once quite wealthy!
I think my great-grandmother's name, Keziah Pratley, was pretty good. I was expecting our first child when a great aunt told me about her mother's name. Keziah wasn't a name we were likely to encumber our unborn child with.
