Isalyn, Isaline, and Ysaline are most likely forms of
Isabelle. In
France, at least, the namedays for Isaline is the 22nd Feburary, Saint
Elizabeth's Day.
It has also been suggested that it may come from Ysoie, a French form of Eusebia (masc.
Eusebius).
Another possible theory is that it's a form of Isoline, making it a derivation of Isihild /
Isolde.
