Thank you all for your help, it gives me a lot to go on.
Cheers.
Mary I'm sorry, I havent got to the bottom of the Brew connection yet, all my grandfathers siblings had a middle name Brew as did his father, Alfred Brew Radcliffe, but I havent found the link yet, but its not his maternal parentage as his mother was called Martha Mitchell Kelly. Of course its possible that the link is Alfreds mother who was called Susana born in Douglas around 1815, his father was Robert Radcliffe born in Lezayre around 1813. Please excuse the vagueness of these dates, I've only so far found them on the census!
Thanks once again.
