Sylvie, there is indeed a brief obituary of Robert Taylor in the Hexham Courant of 4th January 1931.
There is no mention at all of any work he did in relation to enemy aliens.
But the good news is that there is a small photograph of him!
Could you email me via outings@hexhamhistorian.org and I will try to arrange to get a copy to you.
