Your information raises the proof of some connection between the Argyll Sinclairs and the Caithness Sinclairs in yet another odd way if what is postulated is correct. If indeed there was a daughter (possibly) of the Sinclairs of Rosslin that became the mother to the lines of Campbells and the especially that of the Dukes of Argyll. It illustrates again the ironies that we can get into even in ones own back yard so to speak. Especially given the early dates involved. Nice and interesting work Sinclair and Donald.
