There was a nice little discussion about the origin of the name Isabel on this board a couple of days ago. I'd like to take up that thread once more, this time the ELIZABETH - ISABEL connection.
My namebooks are rather reluctant about this, stating it as a possible derivation of ISABEL and always considering other options as well (such as ISEBEL). Now I would like to know more about the Spanish side: How likely is it, that a name like Elizabeth would undergo such changes? ELISA and to ISA and BETH to BEL (like in ARABELLA). Are there any parallels for such contractions and changes with other Spanish names? I'm thinking of CARMEN from CARMEL. Any ideas? And what role would ISEBEL play in mediaeval Spain?
