I have a bit of information on this William Samuel OKE. He can be found on the 1880, 1900 and 1910 census and did have daughter Daisy and Mabel. He seems to have come from Canada although one year he was listed as from Australia. I am as yet unable to locate him in Canada or ENgland.
I have an Edwin (vice Edward) OKE who lived in Utah; this man was born abt 1874 in Redruth, Cornwall so much younger than William Samuel OKE who was b. 1843 or 46.
