Search for information of Jacob Goldberg b1900 aka Jack Berry #unitedkingdom


I am searching for the early life of Jacob Goldberg b1900, I don't know where or his parents names. He lived in London and became influential in the anti fascist movement in Plymouth being imprisoned for his actions but continuing to speak out about his beliefs. His partner Cissy Feltham/Hann and Jack had a child in Plymouth in 1934. Jack worked in a number of  fields silver and gold bullion dealing, travelling in canvasses and sable brushes finally ending as a furrier in Yeovil, Somerset. 
He had rather a chequered history prior to Yeovil which was documented in the press during the 1930s.
Any help would be much appreciated.
