I have never heard of this name - but it seems to exist. Wilfried Seibicke (1) lists these names:
GAILE (m./f.) short form of names containing the element GAIL. Variants: GALE / GALEKE / GAELE / GALO / GALKE / GALLEKE / GÄLEKE
(Name element GAIL) Germanic *gail-, Goth. gails, Anglosaxon gâl, Old High German geil, “voluptious, hilarious, boisterous, lecherous”

Considering the fact that only few Americans are able to reproduce Germans sounds like EH or ÄH like in "Besen" (broom) or "Nähe" (proximity) without saying "Bayzen" and "Naya", I would say: Yes, this is the name you are looking for.
