On the recommendation of the speaker, I clicked to the Drouin Collection of Quebec vital records to find Sidney's actual birth record. Here's the direct link to the Drouin Collection's gateway on Ancestry. I clicked on "Quebec Vital & Church Records," then typed "S. Berk," "1914," and "Montreal." In an instant, the search put somebody named "Samuel B. Berk" at the top of the results.
|Samuel B. Berk's 1914 birth record (Sidney Burk in New York)|
|Lily Berk marriage record from June 7, 1931|
AND there was a marriage entry for "Lily Berk" in the Drouin search results, so I clicked. As you can see here, she's the Montreal-born daughter of Abraham Berk and Annie Horovitz, marrying Polish-born Joseph Goldberg (Farber). Both bride and groom lived at 66 Bagg Ave. in Montreal in 1931, when they were married. This address is less than one mile away from Mt. Royal Ave.
More Drouin research is in my future!
