Thank you again for your work on this - it is very much appreciated.
From here, I have already google mapped the address you gave me for Alfred's business (it is now a hair salon) and have done some extra searching for this line of the family (it had come up as a dead end before).
According to Alfred and Hannah's marriage certificate, Alfred's father was a tailor and the names match up with the 1911 Census data so I am confident I have the right family. It appears the only citing of the name in official format is on that Baptism form - which is strange and may just be the tipping point for me to order the birth certificate :)
Many thanks again
