Payn was one of four siblings including Hamo Peverel, parents not identified.
His parentage is confirmed by the undated charter under which “Willielmus Peverel de Brunne” donated property “in Wildene villa mea…Oddewic” to Thorney Monastery, for the souls of “avunculi mei Willielmi Peverel de Doure…patris mei Rodberti Peverel fratris sui, et Hamonis Peverel avunculi mei et…matris meæ Adeliciæ, et…Henrici Regis Angliæ”. The Liber Memorandorum Ecclesie de Bernewelle records that Henry I King of England granted the barony of "Roberto filio Pycoti" in Cambridgeshire to "suo familiari…Pagano Peuerel". A manuscript history of the foundation of Barnwell Priory names “Pagano Peverelle…militi”, in the time of Henry I King of England, as a donor to the priory in 1112. The other references in the same source, quoted below, suggest that Payn must have been an alias of Robert Peverel. "Stephanus comes Moritoni" confirmed the donation to Bec Sainte-Marie by "Willelmus Pevrellus de Dovra" with the consent of "fratrum suorum Hamonis et Pagani", by charter dated 1127.
The Liber Memorandorum Ecclesie de Bernewelle records that "Pagani Peuerel" died just before ten years after the move of canons to Barnwell priory and was buried at Barnwell. 1
