His father died in 1363 when Robert was a minor aged 7, and he became a ward of King Edward III, who granted the custody of his paternal lands to his daughter Isabella of England (1332–1382), wife of Enguerrand VII, Lord of Coucy, 1st Earl of Bedford (1340–1397).[2] He exited wardship having attained his majority of 21 and in 1377 was knighted at the coronation of King Richard II (1377-1399).[2] He rebuilt his ancestral seat as a castle, recorded for the first time in 1389 as Gleaston Castle.[2]

He married twice:
