Hugh Vere Huntly Duff Lucas-Tooth of Teanich by
Royal Licence in 1920 when he gained, at the age of seventeen, the recreated
baronetcy of his maternal grandfather, the first baronet, whose three sons had died in
World War I, being created
1st Baronet Lucas-Tooth, of Bught, County Inverness, in the
Baronetage of the United Kingdom on 1 December 1920, with special remainder to the heirs male of the body of his mother. Lucas-Tooth was first elected to the

Parliamentary Private Secretary to Arthur Samuel,
Secretary for Overseas Trade. Lucas-Tooth was
called to the bar in 1933 at
