Thanks VERY MUCH everyone, particularly Monica L for finding the newspaper obit. - hopefully now I can find the death on SP, and perhaps his first wife through that. Thanks also very much to FIRTHVIEW, my friend, for putting this into the Caithness section; I'm very 'green' to rootschat, and don't really know what I'm doing eg someone pointed out elsewhere in rootschat that the 1911 census said he was a United Reform minister, when I thought it had said free church - I'm clearly hopeless at deciphering the old writing too!!
Anyway, thanks very much to all you genealogical supersleuths out there, I really appreciate the help
