I just stumbled accross this website and thought that we are probably related. My great, great grandfather also settled in East London in the late 19th century - I believe he was a baker who set up a bakery in Shorditch (?). His son, my great grandfather, was instrumental in taking the police on strike in 1911 (see Reynolds and Judge 'The Night the Police Went on Strike'. I'd love to know more. Has your cousin finished his research?
