It makes sense considering Yiddish doesn't have vowels and therefore it causes a vowel shift between German Yiddish and other Yiddish dialects. thank you for confirming this
but It also appears to be used in Medieval Silesia by Germans, I should've made it clear but I can't understand what is the German usage of the name, the silesian German name list probably consists of gentiles, I don't see a reason why would a Jewish name on the list. Is it a German contage of Gittel?
