The 1940 Jewish Year Book was the first to separate Wales from the rest of “The Provinces”. The information was compiled in 1939, and so this listing gives a picture of the Jews of Wales on the eve of the Second World War.
Newport has been included here, although it is listed in England in the book.
Rabbi Moses Elias Rogosnitzky, formerly Dayan of Leipzig, is Rabbi of Cardiff.
For a book published in Tredegar, with subscription lists (in Hebrew) that include several Welsh Jewish communities, see: Zecher Ov, published by Rev. Henich Olivestone in 1916.
