There do not appear to be any burials recorded for George around the relevant time. Also the last two baptisms for George would occur when another George aged about 10 was living.
Also the baptisms of Albert Frederick a few months apart, while not impossible, don't seem to fit in.
All this is assuming that we are talking about a single family, which given the names of the parents seems very likely.
As usual, working form the IGI causes more questions than answers. The PRs may give some additional, vital information.
