Ok thanks Ian.
My ancestors in Durness are only found on record there in one instance. In 1791 my great-great-great-great grandparents Alexander Munro (a carpenter) and Barbara Mackay are found in Cenabeinne at the birth of their son James Munro in 1791.
However after that they are found again in the parish of Farr in 1796 where they had yet another son called James, so presumably the first James who was born in 1791 in Durness died young. They had a total of 6 sons and one daughter in the parish of Farr between 1796 and 1812. On these records he is recorded by the spelling of "Alexr Munro". I am descended from their youngest son Mackay Munro born in 1812 (He went by the name of Mackay John Munro). They owned an Inn in the village of Armadale , parish of Farr which Barbara Mackay ran. I also have records that say Alex Munro was a master carpenter, house carpenter and boat builder.
Now going back to Durness where they were in 1791, there are several other genealogists who have matched Barbara Mackay (the mother in 1791) to the parish birth record of the 15th November 1768, daughter of John Mackay of Sartigrim. What their reasoning is for this I am not sure. However I have managed to match almost all the Barbara Mackays born in the parish of Durness between 1764 and 1770 to marriage records in the same parish. The only one I am left with is the Barbara Mackay born on the 15th Novemebr 1768 in Sartigrim, daughter of John Mackay.
To take things further the Barbara Mackay born on 15th November 1768 in Sartigrim had two sisters: Janet born 1766 and Ann born 1771, both daughters of John Mackay of Sartigrim. On the 1771 record for Ann's birth the mother is also named as Barbara Mackay, so it seems more than likely that the Barbara Mackay born in 1768 was named after her own mother.
So the elder Barbara Mackay is recorded in 1771 by the Gaelic alias of "daughter of Donald, son of George of Skerray". Which some people have linked to George Mackay of Skerray who is listed on page 315 of the Book of Mackay and was living at just the right time.
My only real problem is confirming that my Barbara Mackay who was mother in the parish of Durness in 1791 is in fact the same Barbara Mackay born 15th Nov 1768, Sartigrim , parish of Durness. My Barbara Mackay is actually found on the parish of Farr 1841 census aged 75 - but all of the ages for adults on that census have been rounded to a multiple of 5. Some rounded up, some rounded down. If she is the one born in 1768 then she would have been about 73 in 1841 which could have been rounded to 75. Also her youngest son, Mackay Munro who I am descended from often went by the name of John Munro or Mackay John Munro - and was therefore possibly named after her father John Mackay of Sartigrim.
Interestingly there is no marriage record for Alexander Munro and Barbara Mackay.
Hope you find this interesting.
