I am sure that I saw the entry on the 1901 Census.... the original, not the transcribed record....a few years ago, on the far right hand side of the document.
I remember that it was free to search the census on the internet at that time.
Now, some more information has come to light about the possible town/village origins of the family.
The late Bud Flanagan of the Crazy Gang, was a cousin. His real name was Chaim Weintrop.
