If you look in Familysearch.org, you can find Hunter Ritson's birth, marriage, and entry in 1881 census - free!
In the 1891 census he is a grocer and provision dealer age 40. His sister Grace [mistranscribed as Genie

] age 35, house keeper, is with 3 grocer apprentices, nephews, John Savage age 19, John R. Whiting age 22 and William H. Whiting also 19. There is also Wilson Whiting age 12 a scholar, and Sarah Lyson, servant age 22.
