How might I find out the name of the incumbent in the Rectory, Jonesborough, in 1915?
Background:
I am pursuing information on Alexander Linton Davidson, born 27 August 1999 in Montrose, Scotland. He became a pharmaceutical chemist and in 1911 was a boarder in the home of Arthur Craft in Chiswick.
On 5 August 1911 he married Sarah Eleanor Winifred Gordon in West Ham.
In 1911 Sarah was a pharmaceutical student, aged 23, born in Argentina, living in the household of her cousin George Henry Turner, wholesale stationer, at 35 Rosslyn Hill, Hampstead. The Camden school admissions register describes GHT as her guardian.
George Henry Turner was born in Birmingham in 1846, son of George Turner, Wesleyan minister, and his wife Mary Calder.
On 9 April 1915 Alexander enlisted in the Gordon Highlanders. He was discharged on 14 May 1915 because of defective eyesight. His wife's address was recorded as 35 Rosslyn Hill, Hampstead, but this was later crossed out and Jonesborough Rectory, Flurrybridge, Co Armagh, Ireland was written in in its place.
Even more confusingly (well, to me at least) Alexander's address on discharge was 7 Pavilion Road, West Bridgford, Nottingham.
I have not found Alexander and Sarah in the 1921 census or the 1939 register, or in any other records I have tried after 1915, so I suspect that they may have emigrated.
