A manuscript history of the Lacy family names “Edmundum de Lacy comitem, constabularium Cestriæ”, born in 1230, as son of “Johannes de Lacy primus comes Lincolniæ” and his second wife, but adding that he predeceased his mother and therefore did not succeed as Earl of Lincoln.
He succeeded his father in 1240 as Earl of Lincoln, although he does not appear to have been formally invested with the earldom. “Edmundus de Lascy constabularius Cestriæ” donated property to Roche Abbey, for the souls of “patris mei Johannis de Lascy et Margaretæ matris meæ, et Alesiæ uxoris meæ”, by undated charter.
The Annals of Tewkesbury record the death in 1257 of “Eadmundus de Lacy frater Matilidis comitissæ Gloucestriæ” and his burial “apud ---”. 1
