The Thomas Howse you mention from the 1871 census is probably Thomas Howse, b. 1788 in Aynho, Northampton, Eng., died 1874, in Pilkington, Ont. He married Mary Churley, b. ca 1787 in Aynho. My great great grandmother, Hannah Howse was a daughter of Thomas's brother John. Thomas's parents were John and Mary. Somewhere I have some information on Thomas's children.
