Has a Royal Navy officer ever commanded a ship named after one of that officer's ancestors?
Short answerA member of the Duncan family may have commanded one of the ships named Duncan, but the recollection is uncertain and no equivalent Collingwood or Nelson example comes to mind.
NotesThe likely case involves a member of the Duncan family commanding a Royal Navy ship named Duncan. This recollection is explicitly tentative because its source could not be identified during the stream. No remembered example connects a Collingwood descendant with HMS Collingwood or a Nelson descendant with HMS Nelson. This is therefore a lead for record checking rather than a confirmed historical claim.
