Information on William and his wife taken from a family tree found on familysearch.org, that connects with Hubert Storey. In the 1871 census, he was in the Muskoka district of Ontario, and was listed as a shoemaker.

As of the 1881 census (where they are listed under the last name ‘Hard’), only George, Thomas, Alice (mis-spelled Alis) and Elizabeth are still living with the parents (Muskoka district, Township of Monck).

There is a record at https://familysearch.org/pal:/MM9.1.1/JF47-2P2 that shows a William Hard of Sussex, born in 1816, passing away in Toronto on October 21, 1895. Likely this is him.
