Hi Diane.
Were you aware that your grandfather was the adopted son of Emma 
Sleigh.
In 1891 she calls him her son but I thought it unlikely because of her age
and then in 1901 he is adopted son.

It may be interesting to obtain your grandparents marriage certificate to see if Victor names his father.
