Thanks Nicholas for responding.
I do not have an exact date of birth, as I thought it would be impossible to
get the correct certificate from Ireland with just his name, knowing how many
Murphys there are in Ireland.
He s on the 1840, 50, English Census, easy to pick up as his wife's name is
Rhoda and hs firstborn John William..
I haven't got access to the census records at the moment, but I tend to think he
was born about 1801.
Is that any help ?
