Its a character in the book '
Johnny Tremain' and I know
Paul Revere used it as a name for one of his daughters. The etymology seems a bit dicey- possibly a combination of
Isabella and
Susannah or maybe related to the name Ysanne. Either way it was used at least a little bit from the 1700s but has never hit the top 1000.
WDYT? I'm really quite liking it.
