Thank you, I have enlarged it as I had not noticed that there were letters at the end. I wonder whether they could be the initials of the priest when he made the change!
Given the information that I have everything seems to fit, ie addresses and occupation in the 1911 census, names of siblings except for this surname of McCarroll which ought to be Hanna. He was a sailor who met an untimely end in Liverpool docks in 1922 by being crushed between a ship and the dock wall and this was registered in the name of Hanna(h) - Liverpool coroner.
