William Shaw Mary Jordan Burns Family History

Like to find information about my great-grandparents William Shaw born 1779 Tipperary Ireland & Mary Jordan born19/03/1820 Wexford Ireland. They married Geelong Victoria 1841 I believe. Possibly William was a seaman ? Anyway would be great to know something of their early years in Ireland & wherever they landed & lived on arrival in Australia. Both died in 1885 & are buried in Harrow Victoria.
