Thanks, Monica. Just taking another look at this "brick wall". The shipping register shows her parents were Donald & Elizabeth. I think they are the earliest record available, which has her parents named.
Yes, I have traced Eliz Graham Taylor from 1841 census, through the 1851 census. I have that in my notes. The age for Graham is about right, as in other options that have been suggested by other descendants, but again, they are all possibilities.
Regarding the couple I found in Nairn, I wonder if a teacher was classed as a "Burgh officer"?
Regards
Judy
