I do not know of any other Roger who is likely to have been thus addressed. We are given by Gervase de Cornhill a further clue as to his parentage in a charter of his, under Henry II., in which he mentions Ralph fitz Herlwin as his uncle ("avunculus"). Ralph fitz Herlwin was in 1130 joint-Sheriff of London.[906] This clue, therefore, is worth following up. Now, Ralph must either have been a brother of the father or of the mother of Gervase. It is highly improbable that Ralph "filius Herlwini" was a brother of Roger "nepos Huberti," each of the two being always mentioned by the same distinctive suffix. It may, therefore, be presumed that Ralph was brother to Roger's wife. Now, we happen to have two documents which greatly concern this Ralph and his son, and which belong to one transaction, although they figure widely apart in the report on the muniments of St. Paul's.[907] Nicholas, son of Ælfgar, parish priest of the church of St. Michael's, Cheap, a living which, like his father before him, he held at lease from St. Paul's, exercised his right to the next presentation in favour of a son of Ralph fitz Herlwin, who had married his niece Mary. From the evidence now in our possession, we may construct this pedigree:— "Algar Colessune,"[908] "Herlwin." priest of St.Michael's, | Cheap. | | | +-------+------+ +-------------+-------+------+----- | | | | | Nicolas, [dau.] = Baldwin Ralph William Herlwin priest of | de Arras. fitz fitz fitz St. Michael's, | Herlwin, Herlwin,[909] Herlwin, Cheap. | joint-sheriff living 1130. living 1130. | in 1130. [909] | | | +------+----+------------+ | | | | Mary = Robert William. Herlwin. fitz Ralph, inherited the living of St. Michael's from his wife's uncle.
