1. Robert married firstly, Juliana Percy. Their child was:
John Conyers of Ormsby, b. 1355, his son and heir, who seems to have died in his father’s lifetime, and left a son Sir Robert Conyers. who was living in the 14th Richard II. Anne, his daughter and heiress, married James Strangways.

By his marriage with Juliana daughter and heir of John Percy the younger Robert became lord of Ormesby in Cleveland. (fn. 63) He died in 1390, leaving by her a son Robert, who was heir to his estates in Coatham and Ormesby. (fn. 64) The younger Robert was already settled at 'Stubhouse' in February 1382–3, when Elizabeth his wife was co-executrix with Sir Robert Conyers of the will of Goscelin Surtees. (fn. 65)
The heir of the younger Robert was his son John, apparently the Sir John Conyers of Ormesby who died in 1438. (fn. 66) Coatham is not mentioned in Sir John's will and does not subsequently follow the descent of Ormesby, so that it is probable that it was given to a younger son of the house.
Clay's Pedigree
https://www.wikitree.com/wiki/Percy-127
Clay's pedigree is at odd's with Ord's (as well as Graves'). The latter appears to make John of Ormesby (will 02 Jun 1438, proved 18 Jul 1438), a son of Robert Conyers and Juliana Percy, which contradicts Raine's (1836) footnotes in a transcription of the said's will.[2]
