  • 'Thweng1'
  • TCP reports the suggestion that "the family originated in co. Durham, being related to the FitzMarmadukes, lords of Horden" and that there was a connection with the village of Thwing in the East Riding of Yorkshire.

      • Walker (which also named his mother as an Emma), BE1883 & Commoners all identify Marmaduke's wife as Emma, sister of Duncan Darell, but we follow TCP in showing that Emma as Marmaduke's mother. TCP does not identify Marmaduke's wife.
        • i. Sir Robert de Thweng (b 1202, d 1247)
        • BE1883 & Commoners identifiy Robert's wife as the widow of Sir John de Oketon. TCP & Walker identify her as ...
        • m. Maud/Matilda de Kilton (d 06.1279, dau of Roger de Kilton, brother of William, widow of Sir Richard de Autrey)
          • a. Sir Marmaduke de Thweng of Kilton (b 1225, d c1283)
          • Walker identifies Marmaduke's wife as dau of Peter de Brus of Skelton by Helewise, dau of Peter de Merley, and sister/coheir of her brother Peter. Commoners identifies her as Lucia, sister/coheir of Peter de Brus of Skelton. As shown on Bruce01, we follow BE1883 (Lancaster) (and other sources which show the Peter who married Hilary (not Helewise) de Merley as having dsp) and TCP which shows this Lucy as ...

              • (H) Maud de Thweng
              • Walker shows a daughter Maud as married to Sir John Hotham and mother of another John (b 1344, a 1401). This appears to be wrong. TCP identifies the Maud who married that Sir John as a daughter of the above Margaret de Thweng and Robert de Hylton.
              • (I)+ other issue - John (b 1284, d 03.01.1361, prior of Bridlington), Nicholas (b 1286)

              • (A) Sir Edmund (or Edward) de Thwenge of Cornburgh (Corneburgh) & Southburn (d 15.10.1344)
              • (1) This man is named Edward by Commoners & BE1883, showing him as a generation earlier (SIr John not being mentioned). We are following Walker who names him Sir Edmund and shows him as son of Sir John but note an element of caution as Walker shows Margery, who married Ralph, Lord Neville, twice, both as sister and as daughter of Sir John.
              • (2) Commoners & BE1883 mention only his marriage to Alice Helmesley and Commoners confirms that she was mother of Marmaduke, William & Walter. Walker shows that he also married Isabel Constable and, in his article on 'Thwenge of Over Hemsley', shows that it was Isabel who was mother of Marmaduke, Walter, William & John. Provisionally we follow Walker rather than Commoners in showing Isabel as mother of all of the sons.
              • m1. (by 1320) Alice de Helmesley (dau/heir of Walter de Helmesley of Over Helmesey)
