Hi Kylie,
Actually, looking over the sources for this family, there are a couple of discrepancies!
I got the Angus MacGillivray/Marg. Campbell marriage info from a transcript of Daughter Christy's death cert, dated July 9, 1888 at Drumfearn.
But also in my notes is this:
(Notes from Catherine King, copied from the Register at Portree Library.)
Christina McClure, died 9/6/1888, at Drumfearn, aged 66 years, w. of Charles McClure (crofter), f: Angus McGillivray, crofter, m: Margaret McClure.
"It is not clear whether Christy's Mother was Margaret Campbell (from transcription of death certificate) or Margaret McClure from the above transcription. Also, there is a discrepancy on the date of death - June or July of 1888."
There is a possibility that the info on the death cert is incorrect, I haven't seen the original, but the transcript notes that the informant was Christy's Brother - Donald.
Did you get the details of Angus' first marriage to Mary McLure from his death cert? When your move is over with, I sure would be interested in getting more details from you.
It would appear that these families are one and the same, and that the info regarding Margaret Campbell as being the Mother was not right!
Here is the family of Angus & Helen from the 1841 - all listed under MacGillivray.
