should read: Our family having arrived from Suwalki and Germany in the late 1860s there were no members left who learned Yiddish at home. It was not the Mameh loshen. We attended the local yeshivah high school in the mornings and took academics at the public high school afternoons.
Being fluent in both Hebrew (Ivrit) and German made learning Yiddish easy.
