  • Notes 
    • William's mother is often shown as Mary (of Orkney) Sinclair. HoweverDoug Hickling (Dhhic@comcast.net) points out:


      "I am suggesting some changes/additions to the ancestry of Helen Hepburn,and
      her husband John (of Carnwath) 2nd Lord Somerville. John's grandmotherwas
      not Mary (of Orkney) Sinclair, as shown by you, but rather Janet,daughter of
      Alexander (Sir) Stewart of Darnley by his first wife ____ Turnbull,daughter of
      Sir Turnbull of Minto. Alexander (Sir) was descended (in the male line)from
      Alan (Sir) Stewart, the second son of John (Sir) Stewart of Bonkyl and(in a
      female line) from Walter (Sir) Stewart, the fourth son of Alan (Sir). The
      Somerville article in CP12:92, which was published in 1953 and istherefore
      one of the newer CP volumes, states that William Somerville of Carnwathwas
      the son and heir of Thomas (Sir) Somerville and his first wife, Janet,daughter
      of Alexander (Sir) Stewart of Darnley and was born in or before 1400. At
      footnote d, the article says that Thomas (Sir) married Janet Stewartbefore
      July 1391, thus obtaining the barony of Cambusnethan. The same note says
      that he married Mary Sinclair in 1407 and tht it is unlikely that she wasthe
      mother of his son William. Thomas (Sir)' third wife, whom he marriedpursuant
      to a 2 November 1411 dispensation, was Elizabeth Keith, 4th daughter ofSir
      William Keith, who was the widow of Nicholas (Sir) Erskine of Kinnoulland of
      Adam (Sir) Gordon of Huntly.

      Helen Hepburn's father was Adam (Sir) Hepburn, as shown by you, and hermother was Janet Borthwick, daughter of William (Sir) Borthwick, pursuantto a papal dispensation on 2 November 1411, which, by coincidence is thedate of the dispensation mentioned previously. I am getting the Hepburninformation from SP2:135 etc., but the information on the Borthwickdispensation is in the
      addenda and corrections SP9:39. Adam (Sir) Hepburne of Hailes was the sonof Patrick Hepburne younger of Hailes and a daughter and co-heir of thefamily of Vaux. The SP article has earlier generations."

      Also from Doug Hickling

      SCOTS PEERAGE, vol. 8, page 1 etc.
      At page 2, this work lists John as the second Lord Somerville, statesthat he
      married Helen, daughter of Adam (Sir) Hepburn and that they had (1)William the 3rd Lord Somerville, and (2) Elizabeth, who marriedGillsepic or Celestine
      Campbell, eldest son of Duncan (Sir) Campbell. Lord John's parents arelisted
      as William the 1st lord and Janet Mowat. William's parents are listedas Sir
      Thomas "sometimes called lst Lord Somerville" and his wife MarySinclair,
      daughter of Henry Sinclair, lst Earl of Orkney.
