Thank you for your responses so far. I fully appreciate that it is going to be very difficult [if not impossible] to identify my father but, as I only very recently learned of the existence of the cousin, my daughter and I are still actively working on the matter. There are many problems we already know about that complicate everything. For example, Mrs. Brooker, a young widow, came to Hull from Kent to live with her sister and brother-in-law, the Richardsons. Her husband, Charles Brooker, had died as a result of his participation in WWI. But it is not known if Charles Brooker was originally from Hull and related to the many Brookers of Hull--or if he was from Kent.
