I didn't find anything out on Janet I'm afraid.
Anne, son of John and Esther, died 21st March 1915 in Newport, Berriedale age 97 years. She never married. Her nephew-in-law, George Chisholm, was the informant. I have my suspicions that George was actually her great nephew-in-law.
Ann's brother Hugh was the only other person in the family I could find anything out on. He was a master shoemaker and died age 90 in Knockally. He married Barbara Gunn, 1st January 1836 and she died 31st August 1907 age 98 years. They had at least nine children:

That's about all I got, but now I know where the connection is (Janet b1817) I have a clearer idea of what to look for next time.
