Daniel Kennedy and Margaret Donald mrd 6 Nov 1856 Rathsaran emigrated to Canada 1863

Daniel Kennedy (born 27 Feb 1838 in Ireland) and Margaret Donald (born 6 May 1831 in Aberdeen, Scotland) moved to Canada in 1863 with their older son (Edward) George Kennedy, and Patrick James Kennedy (six months old) and settled in Chatham, Kent County, Ontario, Canada.  Son Patrick James was born on Sep 28, 1862 and baptized by Henry Herbert on Nov 30, 1862 in the Parish of Rathsaran in the County of Queen's (entry number 13). They were living in Rathsaran and Daniel is shown as a pensioner.  He served in the Crimean War and was injured several times.  He and Margaret died in Essex, Ontario and are buried there.  My father-in-law is 94 and Daniel is his grandfather.  Any local or ancestral information would be appreciated as I would like to be able to pass it along to him.
