# Srul Izaak Barbanel (b.1904 Uhnów) — how is he related?
**Question:** how is Srul Izaak Barbanel (b.10 Dec 1904, Uhnów/Galicia; m. Ciwia Stransgerstel-Lechner, Rava-Ruska 1929; son Natan Aron Gedalja b.1933 Lwów) related to [[Srul Icek Barbanel (b.1829)]], son of [[Nusyn Barbanel (b.1798)]]?
## What's PROVEN (Yad Vashem Pages of Testimony, submitted by Sura's nephew **Mordekhai Abarbanel**)
- Srul Izaak's surname is **matrilineal** — his father was **Szloma Katz**, mother **Sura Barbanel** (Galician religious-only marriage → children take mother's name).
- **Sura Barbanel = "Sara Katz"**, b.1884 Uhnów, d.1942; her parents were **Shalom Barbanel & Khava**; married Szloma Katz. (YV item 1090385.)
- Sura's **brother = Moshe Tzvi / Moses Hersch Barbanel** (b.1886, Uhnów; wife Henia Beila Scheck of Oleszyce) — confirmed by the Uhnów 1907 birth record + Mordekhai's POTs.
- So: **Sura & Moshe Tzvi are children of Shalom Barbanel & Khava.** Both named a son **"Srul Izaak / Izrael Izak"** → Ashkenazi naming points to a **common grandfather named Srul Icek = Shalom's father**.
## Current best answer
`Srul Icek → Shalom Barbanel (×Khava, in Uhnów by 1884) → Sura (×Szloma Katz) → Srul Izaak (b.1904)`
Srul Izaak is most likely the **great-grandson of *a* Srul Icek** — but **probably NOT [[Srul Icek Barbanel (b.1829)]]**.
## Why probably NOT our Srul Icek (1829)
Pulled the **full Głusk Barbanel corpus** (137 JRI records; Głusk births indexed 1826–88). Srul Icek (1829) × Sura Szandlja Nissenbaum's children are fully documented — and there is **no surviving son "Shalom/Szloma"** born ~1855–65. Absence in an indexed period is meaningful. Combined with the family being rooted in **Uhnów (Galicia)** and Mordekhai's use of the full **"Abarbanel"** spelling → the Uhnów line looks like a **separate, likely Galician, Abarbanel family**.
## Hypotheses
| # | hypothesis | confidence |
|---|---|---|
| A | Separate Galician Abarbanel family; not descended from Srul Icek (1829) | ~60% |
| B | Connected to the Lublin Barbanels further back (shared deep ancestor), not via Srul Icek | ~25% |
| C | Shalom really is an unrecorded son of Srul Icek (1829) who moved to Uhnów | ~15% |
## Next steps
1. **Shalom Abarbanel's birth/marriage (~1855–1882)** — absent from all indexed Lublin + Galician sets; means un-indexed **AGAD Rava-Ruska** registers (b.1816–1900) or Tomaszów Lubelski. Names *his* father (the real Srul Icek) + birthplace → decides Galician-native vs Lublin-migrant.
2. **Autosomal DNA** — Srul Izaak descendant vs a known Głusk/Ostrów Barbanel descendant.
3. Read the "Izrael Izak Abarbanel b.1908" POT (Multiple Sources) for extra detail.
