That's a great shout, Carol!
I can't find him in 1911 so am guessing that he was either in the armed forces or was hiding!
P.S. I've just found this entry on Ancestry which could be the same person:
Name: Arthur R Crouch
Death: West Ham, Essex, England
Death: Oct-Nov-Dec 1948
Volume: 5a
Page: 572
The original says "Alfred R.....60" and there is an Arthur R on the next line who was 68, it appears that Ancestry got mixed up.
