https://yiddishsong.wordpress.com/tag/conversion/: "When ballads have been presented on the Yiddish Song of the Week we have sometimes emphasized the parallels with other international ballads. This week we present a ballad type that is not to be found internationally, certainly not in the Anglo-British-American tradition – a ballad that describes the conversion of a child to the Christian faith; a shmad-ballad. The verb shmadn in Yiddish means to convert to Christianity."
You'll find two related songs on the page, conversations between a parent and a daughter, with the parent offering clothes, a dowry, a good Jewish husband to the daughter if she will return to the faith of her family.
