This would be the Johnston family originally from Drumsaragh, I would imagine. Is this James the one born 14 May 1826 and baptized at 1st Kilrea Presbyterian on 16 May 1826? I have lots of photos of Drumsaragh, from a visit in August. - and also have the valuation map for Drumsaragh Townland (1860). Possibly Derek Torrens can help with the Torrens side.
