Do you have a birth date for him?
His marriage and death registrations will have more information on him.
There seems to be people named George in that family that appear and disappear.
1901 census has a George V b 25 March 1890 with the family.
1891 census has a Cecil, aged 1 so they could be the same person.
1911 census has a Cecil b May 1891 and Edna b May 1891 and no George or anyone born 1890.
1901 census has Edna's birth date as 25 May 1892.
1921 census has a Cecil Miller, aged 30 in Stanley Huron. He is a farmer, single.
Census are notorious for wrong information.
George Howey Miller, b 6 Sept 1884, Huron, s/o George Miller and Emily Streep.
On looking at the original I think the second name could be Harvey.
ON 1891 census there is a Howard Miller, aged 8, which would fit in with the age of George Howey/Harvey.
1901 census has Howard born 16 July 1882 and no one born 1884.
