A great help has been Donovan Murrells who runs a one name study of MURRELL(S) and who has a wealth of information which he is only too happy to share with fellow Murrell researchers. He is not on the internet but can be contacted at 428 Bedonwell Road, Abbey Wood, London, SE2 0SE. 

If you write to him please enclose a stamped addressed envelope - and please be patient - it may take a while but he will reply.
