Thank you for your reply. Yes, this had occurred to me but I can find no record of the death of young Janet (b. 1727) and they apparently did not leave the area. There is a record of a Janet Blain being married in 1746 in Stoneykirk, which is nearby. Also, curiously, in the 1727 document the names of both the daughter and mother are spelt with one 'n', i.e. Janet. In the 1741 document, they are both spelt with two 'n's, i.e. Jannet. All very confusing. It's doing my head in. And to bring it back to my original point, I have just noticed that of eleven consecutive entries before and after Jannet in the 1741 document, eight of them are named Jannet. What are the odds? Seems to be a limited selection of names back then.
