This theory about a certain Rawlinson inventing the philabeg was propagated by the late Hugh Trevor-Roper (Lord Dacre) who loved to debunk received wisdom about Scots traditions. Recent scholarship has since debunked his Rawlinson canard with primary source images of philabegs being worn earlier from at least the late XVIIth century. Trevor-Roper (despite authenticating the phoney Hitler diaries) did (and still does) have some standing as a serious academic historian but he was an incorrigible Scotophobe. This is worth bearing in mind whenever reading T-R's works as they pertain to Scotland and the Scots.
