This is not J M Barrie's sister. This Mary Ann was born in Kirriemuir in 1870, the daughter of James Barrie, born 1846, and married to David Jack. As part of my research for a Roll of Honour of Scotland's WW1 dead, currently working through The Black Watch, I found her sons - David Jack and James Barrie Jack - and wondered if there is any connection to J M Barrie's family, although the second son is more than likely named after her father.
Would anyone know if this branch of the Barrie's was connected to J M's?
