Provisional sub-clan designation: South-Western Bohemian Porges (Klatovy / Klattau and Plzeň / Pilsen).

This branch is reconstructed from three obituary documents: Sofie Mendl née Porges (Klatovy, †11 May 1914), Therese Fröhlich née Porges (Prague, †11 April 1930, « hochbetagt »), and Sofie Porges (Pilsen, †4 March 1936). The first two clearly form a sibship of three (Sofie, Therese, and a brother Josef Porges). The Pilsen 1936 entry, with its husband also named Josef Porges, is potentially linked but unconfirmed.

This branch may be related to the existing Salomon Porges 1842–1918 page, which documents the older Porges line of Neuern / Nyrsko (the Klatovy district). A direct link is plausible but not yet established.

Klatovy sibship (parents unidentified; b. ca. 1840–1855):

Sofie Mendl née Porges (b. ca. 1846/47, d. 11/05/1914 Klatovy/Klattau, in her 68th year, after a short severe illness). Married Mr. Mendl (predeceased before 1914). No surviving children named — likely childless or all children predeceased. Funeral 13/05/1914 from the « house of mourning in Klattau ». Announced only by her two siblings (Therese and Josef), confirming the small surviving family circle.

Therese Fröhlich née Porges (b. ca. 1840–1850, d. Prague 11/04/1930, « hochbetagt » — i.e. of advanced old age). Married Mr. Fröhlich (predeceased before 1930). Buried Strašnice 15/04/1930 at 15:45.
Sole announcer: Julius Fröhlich, son, « in the name of all relatives ». Family had relocated from Klatovy to Prague at some point between 1914 and 1930.

Josef Porges (alive 1914) – named brother in the Sofie Mendl 1914 notice. Not named in the 1930 Therese Fröhlich notice; presumably deceased between 1914 and 1930 OR omitted from the very minimalist 1930 announcement.

Pilsen branch (potentially linked, identity to be confirmed):

Sofie Porges (maiden name not given; d. 04/03/1936 Pilsen). Buried Jewish Central Cemetery, Pilsen, on 06/03/1936 at 14:15. Married Josef Porges (alive 1936).
Children: Ernst, Leo, Karl and Gretl Porges. Grandchildren: Kurt and Jiří Porges. Buses for mourners departed at 14:00 from the Hotel Continental, Pilsen.

Notes

The given name Jiří (Czech form of George) is the first explicitly Czech-language given name in this branch's documentation, signalling Czech-cultural inflection of the family in the inter-war Czechoslovak Republic.

The notice is among the most secularized in the corpus — no religious formulae, no maiden name, no age — entirely civic-administrative in tone. It was published less than three years before the Munich Agreement (29 September 1938) and the German occupation (15 March 1939).

Holocaust trajectory: The Plzeň Jewish community was deported in January 1942 to Theresienstadt and onwards. Of approximately 2,600 Plzeň Jews deported, only ~204 survived. Every named individual in the 1936 notice — Josef, Ernst, Leo, Karl, Gretl, Kurt, and especially the child Jiří — was almost certainly within the deportation cohorts. Cross-checking with holocaust.cz, Yad Vashem and the Terezín memorial is a top priority.

One probable match in the Vienna transports list: Karl Porges b. 29/07/1924 — possibly the « Karl » named as son of Sofie of Pilsen (if Karl was a teenager in 1936 he could have been born 1920–1925). Verification pending.
