DPB records the 10th Lord Grave's 2012 m to Margaret Eileen dau of Ronald Grant WORMALD but gives not issue from this marriage (neither in print nor online).
Ronald Wormald’s legacy notice mentions four sets of children and in-laws ending with ‘Margaret and Tim’ and then lists four sets of grandchildren ending with ‘Eli and Amos’ – assuming Eli is a dau, could AMOS be the son and ha of the 10th Baron?
