A manuscript history of the Lacy family names “Hilbertum et Henricum” as the two sons of “Robertum Lacy” and his wife “Matilda”. “Illebertus de Laceio” confirmed the donations made to Pontefract by “pater meus Robertus de Laceio” by charter dated to [1135/6 Feb 1141], witnessed by “Willelmo Folioth, et Henrico fratre meo, Rogero Pictaviensi et Warnero”. “H. de Laceio” confirmed the donation to Pontefract made by “domina Aliz uxor Rogerii de Molbrai”, for the soul of “prioris domini sui Ilberti fratris mei”, by charter dated to [1147]. A list of fiefs of Bayeux church, dated to [1133], records “feodum de Lacey in Campellis” held by “duorum militum...Guilleberti et Henrici”. The reference to Henry de Lacy, rather than his brother Ilbert, suggests that this source is more correctly dated to the late 1140s. “Henricus de Lasci” donated property to Pontefract Priory, for the souls of “patris mei Roberti de Lasci et Matilildis matris meæ”, by undated charter. King Henry II pardoned “Henrico [de Laceio]” for all his actions during the war (“quicquid ipse forisfecerit in guerra antequam pax facta esset inter ipsum Henricum et regem Stephanum”) by charter dated to [1154/1156]. “Henricum de Laceio” founded Kirkstall Abbey, for the souls of “Ilberti avi mei et Hawis uxoris suæ…et Matildis amitæ”, by undated charter. “Henricus de Laceio et uxor mea” confirmed a donation to York St. Peter by charter dated to [1165/75]. The Red Book of the Exchequer refers to "Henricus de Lascy xliv l xv s, de novo xxxl xvi d" in Yorkshire in [1171/72].
A manuscript history of the Lacy family records that the death “in terra sancta VII Kal Oct” of Henry de Lacy, adding that his burial place is unknown. 1
