The pupil registered immediately before St Thomas Carbur on the school record is Ernest Blundell, son of Edward, of....52 Messina Avenue!
Benedict uses the surname Carbur in the 1891 census, 1893 electoral regeister and 1901 census.
He is 'Carbury' on the 1891 electoral register, then becomes 'Rosscarbur' on 1905 & 1908 ERs and in the 1911 census! Sadly, I have no idea why. Possibly trying to avoid being found by his wife Winifred?
