Many ballads of the British Isles codified by Francis Child have versions collected elsewhere in Europe. For instance Child mentioned French and German language variants of "Our Goodman". Yiddish speakers were not so isolated from majority popular culture as you and I may have thought. So since I've come across Our Goodman (Seven Drunken Nights, Dos Daytshl https://mudcat.org/thread.cfm?threadid=7291 and a version of The Elfin Knight https://yiddishsong.wordpress.com/2011/08/01/yo-yo-di-vilst-performed-by-josh-waletzky/ in Yiddish, I'm wondering what else is out there (the older the better). Any suggestions?

Going beyond the Child Ballads to other widespread traditional/folksongs, there is also The Rattlin' Bog aka The Tree in the Wood aka Funem Sheynem Vortsl Aroys https://mudcat.org/thread.cfm?threadid=57991 and I'm sure there are more songs in this category to be found in Yiddish language .
