I don't think that 1844 birth is your Elijah
I was just about to post these details from Bath BMD - and was wondering if that was the male birth entry Rosie posted
It is the same family I was looking at Ladyhawk Do you think we can discount them
Rosie there doesn't appear to be a baptism for the 1844 son of Joseph to see what his first name is
1844 WHITTUCK (boy) Son Of Joseph Whittuck HUGHES Lansdown Bath
These are the only baptism I can find on anc*y for that family - nothing for an Elijah

I can't find anything for Elijah Whittuck born Holcome c 1840
and I can only see the 1881 census and the possible entry for 1871 census
Muffin41 - do you have Elijah on earlier census records?
