Sub-clan N – matriarchal anchor: Anna Porges née Knotek (b. ca. 1845, d. Prague 6 August 1913, in her 69th year of life).

Buried at the New Israelite Cemetery, Strašnice, on Friday 8 August 1913 at 4 p.m. The day-of-week check (6 August 1913 = Wednesday ✓; 8 August = Friday ✓) confirms the dating.

Husband: a Mr. Porges, predeceased before 1913 (identity to be confirmed — a brother of Salomon Porges who signs the obituary "in the name of all brothers- and sisters-in-law").

Children (alive 1913):

• Alois Porges – married Fritzi née Burger (alive 1913)

• Rosa Porges

• Rudolf Porges (resident of Kolleschowitz / Koleč, ca. 30 km NW of Prague) – married Olga née Stein

• Oskar Porges – married Marie née Singer

• Erwin Porges (resident of New York) – married Betti née Groß

Brothers (Knotek family): Adolf Knotek and Markus Knotek (alive 1913).

Brother-in-law: Salomon Porges, who signs the announcement in the name of all brothers- and sisters-in-law.

Grandchildren (named in 1913): Franzel, Alice, Frieda, Curt, Ernst.

Cross-corpus integration

The 1913 obituary of Amalie Porges née Pereles (Sub-clan N matriarch's death notice, 11 December 1913) names a "Fanny Porges, mother-in-law". The strongest hypothesis is that Fanny Porges = Anna Knotek herself, "Fanny" being a familiar diminutive of Anna in Vienna-Prague usage. If correct, this means one of Anna's sons (likely the predeceased husband of Amalie Pereles) was Sub-clan N's male anchor, with daughter Martha Porges (named in the Pereles 1913 notice) being Anna's granddaughter.

An alternative reading — that Fanny is a distinct Franziska Porges and Sub-clan N had two matriarchs — remains formally possible. The chronology (Anna died 6 August 1913, Amalie Pereles died 11 December 1913, four months later) does favour the same-person identification, since "Fanny" was alive in December 1913 and would not have been described as a living mother-in-law if the same Anna had died four months earlier under that name. This argues for the Fanny ≠ Anna hypothesis. The question remains open and warrants explicit caveat below.

⚠️ Reservation: Fanny vs Anna identification is unresolved. The Pereles 1913 notice (11 December) names "Fanny Porges, mother-in-law" as alive — but Anna Knotek died 6 August 1913, four months earlier. Either (a) Fanny ≠ Anna and Sub-clan N has two matriarchs, or (b) the Pereles obituary's mention of Fanny was retrospectively listing the recently-deceased mother-in-law without adjusting the formula.

Holocaust trajectory

The five children, four daughters-in-law, and five named grandchildren were aged ca. 25-50 in 1938. Cross-checking the holocaust.cz database for the named descendants — particularly Erwin Porges of New York (likely the surviving transatlantic emigrant of this branch) and the Kolleschowitz line through Rudolf — is a high-priority next step.

Note: the Vienna deportation list contains Erwin Porges b. 16/07/1891 → from Malines (Belgium) to Auschwitz 19/04/1943. If this Erwin is Anna's son who emigrated to NY, the deportation record may indicate a return to Europe before WWII. Verification through US Census records (1920, 1930) would settle the question.
