In Fox 68 he is wrongly called a priest.

He was Lord of Ockbrook (DUGDALE).

His family tree is given in C40.  His wife was Ermentrude (CLARK) Talbot (C40).
He was the son of Serlo de Grendon (WARD), nephew of William FitzRalph (C40), the cousin of Matilda de Salicosa Mara (WARD).

*He called in a prior and 6 canons from Tupholm Abbey (Lincs) to make a 2nd attempt at founding Depedale Priory (WARD, C40) *Serlo, his father, did this (CLARK).

*He called in a prior and 4 canons from Welbeck Abbey (Notts) to make a 3rd attempt at founding Depedale Priory (WARD, CLARK).  The prior, previously prior at Welbeck, was called Benfitz (CLARK).

He was the co-founder with William fitzRalph of Dale Abbey in *1197 (see Foundation of Dale Abbey) on condition they founded a chantry to say a mass daily for his soul (WILLIS).
‘Divine service should be celebrated every day by a priest in the chapel of Depe Dale, for his own soul’ etc etc;  ‘and that in an inn there, should be placed, on a large table, a daily supply from the convent of bread and beer and distributed among the poor of the neighbouring forest’ (DUGDALE).

His stipulation of daily masses for his soul ‘is probably the earliest record of a chantry foundation in connexion with an English Premonstratensian abbey’ (C/WC p. 267).

Bishop Redman's register in the 15th century says the canons served a chantry, but does not say where.  The Little Church?  Ockbrook?  Chaddesden?

He granted "the chapel of Depedale" to the Abbey (CLARK).
He gave Dale Abbey his lands in Ockbrook (C40) but retained Boyah (KERRY).
