Sub-clan I — matriarchal anchor: Rosa Porges née Biach (b. ca. 1843-1844, d. Vienna, Friday 25 April 1919, in her 76th year of life).

Burial Sunday 27 April 1919 at the Döbling Cemetery. (Day-of-week check: 25 April 1919 = Friday ✓; 27 April 1919 = Sunday ✓.) The 1919 obituary closes Rosa's 20-year widowhood and the matriarchal generation of the Vienna-Reichenau Jacob Porges sub-clan.

Retrospective integration — widow of Jacob Porges (1828-1899)

Rosa is the widow of Jacob Porges (~1828-1899, †13 June 1899, Reichenau) — previously documented in the corpus through the June 1899 Jacob Porges faire-part, which Rosa herself had signed as widow on behalf of her children Dolly and Dicky and grandchildren.

Jacob Porges (~1828 – 13 June 1899 †Reichenau, age 70-71)
   ⚭ Rosa BIACH (b. ca. 1843-44, †25 April 1919 Vienna, age 75)

   ├── Dolly Porges  ⚭  Ludwig BUNZL  (married before 1899)

Bunzl-Biach industrial dynastic alliance

The marriage of Rosa's daughter Dolly Porges to Ludwig Bunzl forged a major industrial-dynastic alliance with the Bunzl family — one of the most prominent Habsburg-Jewish industrial dynasties (Bunzl & Biach paper manufacturing, later Bunzl Group). The Sub-clan I marriages thereby anchored the Porges family in the highest tier of fin-de-siècle Vienna industrial bourgeoisie.

Family in 1919

Signatories: Ludwig and Dolly Bunzl; Dicky and Fritzi Porges.

The minimalist 1919 faire-part (post-WWI, in the immediate aftermath of the Habsburg dissolution) reflects the changed social circumstances of the Vienna Jewish bourgeoisie — substantially briefer than typical pre-1914 faire-parts of the same social tier.

Döbling Cemetery context

Rosa's burial at the Döbling Cemetery (Döblinger Friedhof, Vienna 19th district) places her among the documented Vienna Porges burials analyzed on the Auspitz von Artenegg family grave (Döbling I/1/16) page. Rosa's daughter Dolly Bunzl née Porges (†1932 Döbling Catholic) is also documented at Döbling — the family plot may have constituted a multi-generation Bunzl-Biach burial site.

Holocaust trajectory

Rosa's grandchildren Minnie, Anna, Nelly Bunzl (b. ca. 1890-1898) would have been ~40-48 in 1938 — the prime Anschluss-era persecution cohort. The Bunzl family's pre-war prominence makes the Holocaust trajectory of Sub-clan I a major research priority:

• Search DÖW (Documentation Centre of Austrian Resistance) for Bunzl Vienna transports / emigration records 1938-1945
• The Bunzl family's industrial assets were "aryanised" after the Anschluss; several family members emigrated to the UK and US
• Cross-reference with the Auspitz Döbling cross-reference page for the Vienna burial-site network
