There were multiple examples of traditions and other customs, especially with my dad’s family. For example, on a naturalization paper, my paternal grandfather’s paternal grandfather used his son Stanley’s brit-milah date on the secular calendar (November 26, 1911) as his birthdate. He and my great-great-grandmother also gave two of their sons Yiddish names which those sons used openly: Jankie and Susi. They likely anticipated someday that one of their descendants would discover that they were Jewish (as did my dad’s other families). Their example particularly stands out because they had to flee to “Sumeve” (Yiddish for “Szumowo”) before they immigrated to the United States. They fell out with his mother (whom was forcibly baptized when she was five years old) because they remained hidden Jews by choice to avoid Antisemitism. It’s a longer account than I can give in 1500 characters, and it’s nonetheless fascinating.
