As a child, I lived in Germany and had a (female) classmate whose name was pronounced like the English name Gayla. Recently, I've started wondering how it was spelled. Yesterday, I stumbled upon the name "Gaelle". I wonder if this is pronounced "Gayla" in Germany. I know that in French it is something like Guy-ell, but I wouldn't be surprised to discover that the Germans find it reasonable to pronounce it Gayla - after all, Germans pronounce Gisele as Gee-zell-uh (with a hard g).
Is there a German female name that is spelled Galle (with an umlaut on the a)?
