Hirschel Loebel Katz is named in JRI-Poland as the father of Fabish and Schaje Katz, both born in Langendorf, in 1815 and 1817. The mothers of these sons are named as Eva SAMUEL and Eva PLOCH (probably a mis-transcription of BLOCH); these may be the same person, Samuel being her patronym and Bloch being the surname her father adopted; alternatively, Hirschel Loebel may have re-married between their births.

Marie's 1815 marriage record names her parents as Hirschel Katz and Eva geb. Samuel; she must have been born before 1800 to have been marrying in 1815.

Hirschel Loebel Katz is named as the father of "Loebel KATZ/COHN" in JRI-Poland's record Loebel's 1830 move from Tost to Gross Strehlitz accompanied by his wife Sprinze geb. Bloch; the record cites family number 1733. (The original record names the head of the family as "Loebel Katz al[ias]. Cohn".) The record of Loebel Cohn's 1818 marriage to Sprinze Bloch names his father as Hirschel Katz, places him in Langedorf and gives his age as 28 years, so he was born 1789-90; it also says that his mother (who is not named) is dead.

Records of moves from Langendorf in 1837 and 1839 identify Hirschel Loebel Katz as the father of Samuel Katz and Abraham Katz respecively. As with Loebel Katz/Cohn, both records cite family number 1733, which was allocated to a Hirschel Loebel Katz of Langendorf, so we can be confident that Loebel, Samuel and Abraham are all his descendants.

Based on the date of birth of the earliest of his known children (Loebel in 1789-90), Hirschel Loebel must have been born no later than 1775. His last known child, Schaje, was born in 1817, giving a span of some 27 years between first and last child.

Where does Hirschel Loebel Katz of Langendorf fit into my family? His name (and the naming of his first son) suggests his father was Loebel. The Langendorf Katz line begins a generation earlier with Jacob Hirschel Katz (born 1745), son of Jehuda-Lieb (a cognate of Loebel), and this is where I have tentatively placed him, in the absence of any evidence as to his father.
