- **Łęczna *Akta Miasta* 1720–1747 "Acta inscriptionum sub tempus advocatiae Andreae Budnicki" (APL 35/44/0/1/26, jednostka 1753831, 102 scans) — full Jewish extraction.** New Research note [[Łęczna - 1720-1747 - Akta Miasta]] + companion sheet `Sheets/Łęczna - 1720-1747 - Akta Miasta.xlsx` (40 person-mentions). Book 5 of the WORKING Leczna Akta Miasta Project — a wójt-court property book, lower Jewish density, but with two key clusters: the Rubinowicz kahał leadership and a 1744 post-fire market-stall dispute. - [[Elo Rubinowicz (b.1719)]] — Open question added (MAJOR): **Mortka Rubinowicz was head/elder of the Łęczna kahał 1726–1744, wife Brocha/Brochla** (jednostka 1753831 sc.21 & sc.95); too old to be Elo's brother, so book-1's 1766 Mortka is likely his son/namesake (the candidate brother) or one long-lived man. Advances the existing Mortka Rubinowicz lead; gives him a wife + firm dates. Cited, unproven. - [[Rubin (b.1694)]] — Open question added: the Rubinowicz lineage held Łęczna kahał leadership (Mortka the kahał head, wife Brocha, 1726–44). Cited, unproven. - [[Menachem Mendel Hochberger (b.1770)]] — Open question added (STRONG): almost certainly the "Mendel Michlowicz" admitted to Łęczna citizenship 1789 & likely the "rabbi Mendel of Łęczna" (jednostka 1753829, sc.67/69). Four axes align (Michlowicz=son of Michel→father Ichiel Michel; given name Mendel; b.~1770 Łęczna→~19 in 1789; place) plus the vault's pre-existing "Mendel Michlowicz Hochberger, rabbi of Łęczna" ([[Jankiel Kopel (b.1720)]] bio). Possible marriage to a Kopel daughter (Chaia) would tie Hochberger↔Koplowicz lines. - [[Ichiel Michel Hochberger (b.1739)]] — upgraded the Mendel Michlowicz lead from "watch" to STRONG/near-certain (= his son [[Menachem Mendel Hochberger (b.1770)]]). - [[Łęczna - 1716-1810 - Akta Miasta]] note — upgraded the Michlowicz candidate-match grade from "Low–medium/watch" to "Strong" (identified as Menachem Mendel Hochberger b.1770). - **Filing correction:** moved book 5 ([[Łęczna - 1720-1747 - Akta Miasta]]) + its sheet from the 07 July/02 folder to 07 July/**03** (created today, July 3; books 3–4 were created July 2 and stay in /02/). Split this note's edit-log entries from 2026-07-02.md into this file. Root cause: anchored the folder on sibling files instead of today's date; memory rule added. - **Łęczna *Akta Miasta* 1749–1767 "Acta inscriptionum sub tempus advocatiae Antoni Kopeć" (APL 35/44/0/1/27, jednostka 1753832, 145 scans) — full Jewish extraction.** New Research note [[Łęczna - 1749-1767 - Akta Miasta]] (in 07 July/03 folder) + companion sheet `Sheets/Łęczna - 1749-1767 - Akta Miasta.xlsx` (100 person-mentions). Book 6 of the WORKING Leczna Akta Miasta Project. Highlights: a 1759 Frankist (Contra-Talmudist) baptism petition (6 signatories, sc.138); kahał leadership (1755 "Duchowni" roster sc.31; Łukasz Mortkowicz burmistrz sc.121; rabbi Jutka Prymchowicz 1767 sc.140; Dawid Wójt Żydowski sc.138); the Jewish town-lease arendarze (Judrys, Boruch, Leyba Chaimowicz, Leyba Zelikowicz, Wigdor Jakubowicz); a 1749 market-stall register (sc.120). - [[Jankiel Kopel (b.1720)]] — Open question added: **Wigdor Jakubowicz** held the Łęczna arenda 1762–66 (jednostka 1753832 sc.101/126) = same name as book 4's garrison wine-arendarz (1785–91), so the Jakubowicz line held the town arenda for a generation; Berek Jakubowicz among the 1755 kahał Duchowni. Cited, unproven. - [[Elo Rubinowicz (b.1719)]] — Open question added: **Motka Rubinowicz** continues to 1761 (boundary, sc.90) — same as/near the kahał-head Mortka, bridging to book 1's 1766 Mortka; plus Nachim Rubinowicz (1763). Cited, unproven. - **Łęczna *Akta Miasta* 1768–1789 "[Acta inscriptionum et decretorum]" (APL 35/44/0/1/29, jednostka 1753834, 374 scans — the largest book) — full Jewish extraction.** New Research note [[Łęczna - 1768-1789 - Akta Miasta]] (07 July/03) + companion sheet `Sheets/Łęczna - 1768-1789 - Akta Miasta.xlsx` (345 person-mentions — 2nd-richest of the 7 books). Book 7 of the WORKING Leczna Akta Miasta Project. Read by 19 parallel readers (a first wave was interrupted/killed; the killed slices were relaunched to full coverage). Highlights: a near-continuous Łęczna rabbinical succession (Leybko Symchowicz, Judka Szymkowicz, Jatko/Gutker Szymkowicz); Eyber Mortkowicz kahał treasurer; a 1789 regional criminal inquisition (Natan Lewkowicz, rabbis of Chełm/Lublin/Brześć); the town-building arenda ledger; wealthy Jewish kamienica purchases (Aronowicz brothers 8000 zł; the Kahał buying Rynek houses). NOTE: 111 rows had the file plikid recorded as scan# by some readers — auto-corrected to the true cur= scan before compiling. - [[Elo Rubinowicz (b.1719)]] — Open question added (best-defined lead): **Daniel Rubinowicz**, a recurring individual 1777–1786 (jednostka 1753834 sc.135/144/170, Hebrew-signed) = almost certainly book 1's Daniel Rabinowicz (1782); a concrete cross-book son-of-Rubin, candidate grandson of [[Rubin (b.1694)]]. Cited, unproven. - [[Jankiel Kopel (b.1720)]] — Open question added: Wigdor Jakubowicz attested as Łęczna arendarz 1762–1785 (same man across books 4/6/7, removed to Kodeń 1785); continuing Koplowicz family (Sanel, Lejb, Lejzor, Zanwel, Nachman, Eliasz 1766–1789). The Jakubowicz+Koplowicz double patronymic persists as a leading Łęczna family. Cited, unproven.
