This Richard Sleep immigrated to Ontario with his family and married Catherine Garrity who was born about 1821 in Ireland. They had two children - Mary Jane Sleep born about 1861 and Richard Sleep - born 12 Mar 1863. This Richard Sleep married Ann Deborah Varnell in Toronto on 17 Aug 1887 and had five children.
