Marks Block, the uncle who "caused the arrest" of his 12 yo nephew Isaac Kadetsky

Isaac Kadetsky (10/16/1880-1/11/1944) often encountered trouble in his early years. In 1888, at 8 years old, he led a group of two other children his age, managed to acquire a pistol, and tried to break into a safe. (see post and 1888 and 1892 article). In 1897, they were busted for playing poker by the "Gigantic Sergeant - Big Rufe." They were out for the night and told police that they had "jollied de old man and were goin' to just have a little game- see." (See post and 1897 article)

Here is the volley recorded in the 1888 article between the boys, who were 6-8 years old, and the police.

Police: "Where did you put the revolver? 

Moses Silva (7 years old): "Don't 'member. I frew it down in a cellar. No, I didn't take dose postage stamps. He took 'em." 

Eddie Bougusch (6 years old): "I didn't neever. Ikey took 'em." 

Isaac Kadetsky (8 years old): "No, I didn't. 'oo (you) took 'em, ooself." 

The article goes on to say that "Mrs. (Shifra) Kadetsky brought in the revolver that her child had taken home. She handed it over to the Captain., the hammer at full cock, and the chambers all loaded. The young Kadetsky has been arrested before and is evidently the leader of the two. " 

When he was 12 years old in December 1892, his friend Moses Goldman took $300 from his parents and shared $100 with Isaac. The two then ran away to New York. After spending a week "on the run” in the city, Isaac found his uncle, Marks Block, a tailor residing at 158 Rivington Street. Marks then notified the Essex Police, leading to Isaac's arrest. The Essex Police Court placed Isaac under the care of the Gerry Society. Until now, this uncle's identity has remained a mystery. 

Last night, I discovered Jacob Block's marriage license, dated September 10, 1892. He lived at 158 Rivington Street; his parents were Marx Block and Sarah Cohen. Jacob married Bessi Zitron, the daughter of Jacob Zitron and Paula Sand.

Here is the 1880 US Census (June 11, 1880) for Marks 41 (1838) and Sarah Block 41 yo (1838): https://www.familysearch.org/ark:/61903/1:1:MZ6Q-S2K?lang=en 

Marks' occupation is a tailor. They lived at 14 Essex (the heart of the Jewish ghetto in New York's Lower East Side) 

The following children resided with them:

1. Israel Block, 17 yo (1861/2), England 

2. Jacob Block, 12 (1867/8), England 

3. Kauffman Block, 10 yo (1870/1), England 

4. Simon Block, 7 yo (1872/3) England 

5. Morris Block, 4 (1875/6), England 

6. Henry Block 2 (1877/8) New York 

7. Robert Block 0 (b. 12/1879) New York 

The older five boys were born in England, which is consistent with Jacob's 1892 marriage certificate. The 1900 US Census shows Marks as 60 (6/1840) and Sarah Block as 60 (4/1840).

They were married for 39 years (1861). Tragically, she lists having 14 children, 5 who "remained alive," so sad. They list their immigration as 1873. His occupation is a tailor. 

The following sons lived with them: 

Morris Block, 25 (7/1875), England, Shirt Waist Cutter 

Alias Block, 22, (4/1878) New York, Porter, (Henry in 1880, son number 6) 

Robert Block, 20, (2/1880) New York, Shirt Cutter
