Just looked at my 106th Ed. of Burke's Peerage under Byng Earls of
Strafford and the said Robert would seems to be the eldest son(b.19
June 1962) of Julian Byng formerly Byng(from April 1952,Royal Lic.- 5
Sept 1969 to take Byng name and arms,b.20 Oct 1928) who inherited the
property via the will of his maternal grandfather Edmund Byng,6th Earl
of Strafford(b.27 Jan 1862-d.24 Dec 1951) even though the latter was
succeeded in the peerage by his nephew Robert,the 6th Earl.
