Hi Nyle, The Robert Donald in the 1851 Census married to Jane Galbraith was a GGG Uncle of mine. He was born in 1818 to Robert Donald and Ann McQualter (the Ann in the Census). I believe the family moved to Ireland sometime between 1857 and 1860, which is why you didn't find a death date for Jane. Several of the Donald men, including Robert's brothers David and William, did move to NZ around that time. They are buried at Greymouth. Where was your Robert living?.I have 5 Robert Donalds from Ayrshire in my tree but none married to an Ann Wyllie. Sorry I couldn't help more. Best wishes, Wendy Biddle Sydney Australia
