Have found the marriage but it's somewhat bizarre.
Hellen Turnbull married David Alexander 29/6/1863 Edinburgh - she is shown as aged 20, daughter of Robert Turnbull and Janet Aitken and he is shown as aged 22, Private 25th. Foot, address Edinburgh Castle, son of John Alexander, Gardener, and Susan (formerly Scott).
I could not find any service records for a David Scobie but when I looked under David Alexander found him no problem. He enlisted 30/3/1863 at Edinburgh Castle (discharged 1882) and was bc.1840 Leeds, Yorkshire. When he enlisted he was a gardener, like his father.
So, why on earth is she shown as Scobie when she died, wife of David Scobie, when his surname was actually Alexander?
