  RESEARCH_NOTES: 1. “Royal Ancestry: A Study in Colonial & Medieval Families,” Douglas Richardson (2013): “___ DE CLARE, married in 1171 ROBERT DE QUINCY, Constable of Leinster. They had one daughter, Maud. ROBERT DE QUINCY was killed by O'Dempsey and the Irish of Offaly. Orpen Song of Dermot & the Earl (1892): 285 ("Robert de Quency is not mentioned by Giraldus, though an important personage. From this poem we learn that Strongbow gave him his daughter in marriage [2743], the district of `le Duftir' i.e. the Duffry in Co. Wexford [2748], and the constableship of Leinster [2749]. He was afterwards killed by O'Dempsey and the Irish of Offaly [2408]. He left one daughter, Maud, afterwards married to Philip de Prendergast [2819, see note]. His name appears as a witness to the Foundation Charter from Earl Richard to St. Mary's Abbey, Dunbrody. See Chart. St. Mary’s, Dub., R.S. ii. 154. This would seem to fix the date of this charter, and consequently of Hervey's Charter, to which it refers, in 1172, and not in 1175, as suggested by Mr. Gilbert in the preface; id. p. lxxiii."). C.P. 10 (1945): Appendix H, 100-104 (sub Families of the First and Second Earls of Pembroke).”
