I have had a look at the electoral roll for Cleethorpes without success. However the 1905/1906 Grimsby/Cleethorpes directory lists Richard Williams at 142 Barcroft Street, Cleethorpes, working as an engineer. The 1910/1911 directory lists Richard Williams at 39 Clerke Street, Cleethorpes, and working as a chief engineer. These titles suggest he was working the trawlers out of Grimsby. I have checked the online list of seamen held at the Grimsby Archives. Many Williams but no Richard Williams as an engineer. Next time I am at the archives I will make further enquiries as they have extensive lists which might not be on line. Have you any information which might assist with any further search in the Grimsby/Cleethorpes records.
