Hi,
Regarding origins of names, a school teacher told my father that the Theobald name was of Swiss origin, this would have been back somewhere between 1913 and 1923. I've taken my line back to 1750 and so far no sign of a Swiss origin, all have been Essex born, no doubt the name might well have come over with the Angels Angles or Saxons or some other lot with a Germanic type language.
Family lore can be useful to know but sometimes there is only a grain of truth in it, if any at all, so needs to be treated with suspicion.
Regards.
