Hi Philip & Ros,
My grateful thanks for helping me, I tried the site you advised Philip and ended up sending a request form to them, I had went through all the usual suspects, assisted, unassisted etc, and if they get back to me I will post their reply on here. Ros, here is William's date of birth (should have added this at the start of my query) born 07/05/1827 so around 27 in 1854, as the newspaper has "formerly" Superintendent of Police this would perhaps indicate that he changed his job, to what I don't know, I can't find what job he did before becoming a police officer, he is too young on the 1841 census and married on the 1851 and a Police Officer by then.
Thanks again
