Can I belatedly make a contribution to this conversation? George Fortune of Barnsmuir married, not Helen, but Euphemia Forrester Brown, in 1848. The banns were published in both Kilrenny and Edinburgh, and they were married in St. Stephen's church in Edinburgh's New Town by the Rev. Robert Brown, possibly Euphemia's brother, I haven't checked. Euphemia died in 1906 aged 79 and her death-certificate makes all clear. She was the daughter of the Rev. James Brown & Mary Forrester, the granddaughter of the Rev. James Forrester and Isabella Johnston and the great-granddaughter of Andrew Johnston and Euphame Clephane.
I'm a native of Cellardyke in the parish of Kilrenny, though born 4 miles away in Crail, my mother's home town, and my great-great-grandmother Marjorie Myles of Crail was cook and dairy maid to George and Euphemia Fortune at Barnsmuir House.
