Edgar was living with brother William and wife Olive and family on1891 census in Biddulph. He was single.
1911 census Edmonton Alberta has a Michael Boyd b Ontario April 1856. He is living with son William, b Ont April 1880, Caroline b USA. William is brakeman on railway.
1921 census has a Michael Boyd in Hay River Alberta b 1856 Ontario and he is single.
On 1871 census Ontario there is Gibson Michael 33, George 32 and Phebe 26 living about 4 doors away from the Boyds. Mary's relatives? Men were born Ireland, Phebe b Ontario.
Michael is still in Biddulph on 1891 census, farmer, single.
Possible Gibson parents for Mary Boyd. This follows the Irish naming system.
First son named after father's father [unknown]; first daughter named after mother's mother [Elizabeth]; second son named after mother's father [Michael]; second daughter named after father's mother [Ann -according to 1851 census].
Of course these names are all very common.
The Gibsons and Boyds aren't living that far apart.
