Provisional sub-clan designation: Reach–Porges Prague branch, with double Porges-Reach alliance bridging Sub-clan Y2 (Reismann).

This entry is the document that established the Reach–Reismann–Porges cross-link: Roza's brother Wilhelm Reach married Ruža Reach née Reismann, the daughter of Berta Reismann née Porges (†1907, Sub-clan Y2) — meaning that the Reach family connects two distinct Porges-allied branches through a double marriage: one Reach sister (Roza) married a Porges (Emanuel), one Reach brother (Wilhelm) married a Reismann–Porges descendant (Ruža).

Roza (Rosa) Porges née Reach (b. ca. 1864/65, d. Prague 04/09/1903 at 8:45 p.m., in her 39th year, after a short severe illness). Buried Strašnice Israelite Cemetery 06/09/1903. Husband: Emanuel Porges, « Friseur und Haarhändler » — hairdresser and hair-merchant. The hair-merchant trade was a recognized Bohemian Jewish niche profession (wig-making, postiches), often combined with a barbershop. Son: Walter Porges (presumably young in 1903 — born ca. 1888–1898).

Reach parents and siblings of Roza:

Josef Reach and Anna Reach – parents (alive in 1903).

Wilhelm Reach – brother (alive 1903). Confirmed in the Berta Reismann née Porges 1907 obituary as the husband of Ruža Reach née Reismann, Berta's daughter. Wilhelm thus links this Reach family to Sub-clan Y2 (Reismann–Porges).

Henriette Reach – sister.

Victor Reach – brother.

Pauline Reach – sister.

Holocaust trajectory: Walter Porges (b. ca. 1888–1898) would have been 40–50 in 1938 — the prime adult range for Holocaust persecution. Walter Porges b. 28/10/1887, Spittal an der Drau (Carinthia) – physician – arrested in Vienna 20/09/1943 and deported to Auschwitz 22/06/1944 (last letter 05/11/1944), is documented on the existing SalomonPorges18421918.html page; this Walter is from a different branch (the Salomon-Porges Klatovy line) but the homonymy requires careful disambiguation.
