Jane Roberts (1731-1778), only daughter of Sir Walter Roberts, 6th Baronet (1620), married in 1752 George Beauclerk, 3rd Duke of St Albans. She died in 1778 leaving in her will Glassenbury, a medieval mansion in Kent, to her cousins, the Roberts family of Britfieldstown, nr. Roberts' Cove, co. Cork, they being descendants of the Revd. Thomas Roberts (1590-1664), second son of Sir Thomas Roberts (1561-1627), 1st Bt. (1620). In about 1830, upon his coming of age, Thomas Walton Roberts (1809-1882), second surviving son of Sir Thomas Roberts, 8th Bt. (1620) and 1st Bt, (1809) of Britfieldstown moved to Glassenbury, and took in hand the house and estate. Upon Thomas Walton Roberts death in 1882 Glassenbury passed to his nephew John Roberts Atkin {thereafter Atkin-Roberts} (1843-1913), and there the family remained until c.1976,.^[8][9]

The baronetcy of 1620 is claimed by the 7th Baronet of the 1809 creation.^[8]
