Something is not right in the relationships you've stated - Robert & Lavinia's son George is 11 in 1881 (so would be about 21 in 1891, 31 in 1901) - yet it certainly looks like your Grandfather Edward's father George was 50 in 1901....

Making your Edward's father more likely a
brother of Robert, not a son.....?
