Hi Triumph,
The Ancestral file on the International Genealogical Index has two entries for the birth of Agnes McFarlane daughter of Dugald and Agnes McFarlane (Morrison) one says 1832 Argyleshire and the other says 1834 Argyleshire both have her death as the 27th November, 1876 in Addington, Canterbury, New Zealand and her husband as John Wright. These details are put in by people and need to be proved.
Scotlands People might be a good starting point. You have to register and buy credits and it is a Governament site.
