David Hamilton, 1st of Cambuskeith, +by 1436; He had issue:

• A1. James Hamilton, 2nd of Cambuskeith; m.Marjory (or Mary) Hamilton, dau.of Sir James Hamilton of Preston and Fingalton
  • B1. John Hamilton, 3rd of Cambuskeith; m.Marion Maxwell (+ca 1489, dau.of Sir John Maxwell of Calderwood
    • C1. Alexander Hamilton, 4th of Cambuskeith; m.Marion Cunninghame, dau.of Sir Adam Cunninghame of Caprington
      • D1. John Hamilton, 5th of Cambuskeith, +12.9.1547; 1m: Janet Stewart; 2m: Janet Montgomery
        • E1. [1m.] William Hamilton, 6th of Cambuskeith, +by 1561; m.Christian Farquhar, dau.of the laird of Gilmihsufl ??
          • F1. John Hamilton, 7th of Cambuskeith; 1m: Jane Montgomery of Hazlehead; 2m: Janet Stewart, dau.of Sir Matthew Stewart of Minto
            • G1. [1m.] John Hamilton, 8th of Cambuskeith; m.Janet Cunninghame, dau.of William Cunninghame of Caprington
            • G2. [2m.] David Hamilton of Ludson and Grange; m.Marion Campbell, dau.of George Campbell
            • G3. [2m.] Thomas Hamilton
        • E2. Arthur Hamilton
        • E3. Elizabeth Hamilton
      • D2. William Hamilton of Mackneirstom, later of Sorn and Sanquhar; This connection is being investigated. A web site on Sorn Castle suggests that William Hamilton of Sorn was a younger son of the Udston line rather than of Cambuskeith. The following also looks strange in that the Isabel who married Robert Sempill is shown a generation later than the Isabel (who married George Seton) who is reputed to be the heiress of Sorn, yet the dates overlap. It may be that William of Sanquhar (perhaps of this line) was different from William of Sorn (perhaps of the Udston line); m.by 1518 Catherine Kennedy (a 1533, dau.of David Kennedy, 1st Earl of Cassillis)
        • E1. Sir William Hamilton of Sanquhar; m.Jean (Janet) Campbell
          • F1. William Hamilton of Sanquhar
          • F2. Isabel Hamilton; m.Robert Sempill, 3rd Lord Sempill (*ca 1505, +by 1576)
        • E2. Bernard Hamilton
        • E3. Isabel Hamilton, *ca 1534, +13.11.1604; m.(marr.contract 2.8.1550) George Seton, 5th Lord (*1531, +8.1.1585/86)
        • E4. Catherine Hamilton
        • E5. Agnes Hamilton, +ca 22.5.1609; m.24.2.1542 William Cuninghame, 5th of Caprington (fl 1583)
