Sutherland and Ross Families of Tain

[tookey]

David Sutherland married Ann Ross on the 6th February, 1822 Tain, Ross and Cromarty. Children that I am aware of are Jane, born 1823 Robert Murray, born 1837, Catharine born 1825, William born 1828 and Ann my  GGGrandmother born 1835. All children were born In Tain.  I have Ann's death cert.  It state that David her father was a distiller in Tain.  Could anyone help in finding David's and Ann's Parents.  Ann the daughter came to Australia and married Phillip Richards in Victoria.  Can not find immigration papers or marriage certificate.  So any help will do.
