The Historia fundationis cum fundatoris genealogia of the priory of Abergavenny names “Milonem” as son of “Waltero constabulatio totius Angliæ”. "Walterus de Gloucestria, assensu Milonis filii mei et Berthæ uxoris meæ" donated "ecclesiam de Cernay…ecclesiam… Sanctæ Helenæ de Halgestane…terram…de Westwode in Herchenefelde" to Gloucester St Peter by undated charter. "Walter de Gloecestria, Milo fili ei…" witnessed the charter dated to  which records that "Ricard Puncii filii" granted Aston, Gloucestershire ("Hestoniam") to "Mathilli uxori mee".
Henry I King of England appointed him Constable of England in succession to his father. The 1130 Pipe Roll records "Miloni Gloec" in Wiltshire (two entries). Stephen King of England granted him the honour of Gloucester and Brecknock in  and appointed him Constable of Gloucester Castle. “Mylo constabularius de Gloucestria” donated property to Lanthony abbey, naming “antecessores mei Rogerus de Gloecestria et Walterus constabularius”, by charter dated 1137, supplemented by another later donation (undated) jointly with "uxor mea Sibilla et filii mei Rogerus et Walterus atque Henricus" in the presence of "…Roberto Corbet…".
He joined Empress Matilda on her arrival in England in 1139, acting as her Constable. She created him Earl of Hereford at Oxford 25 Jul 1141, and granted him the castle of Abergavenny. Brien FitzCount, illegitimate son of Alain IV "Fergant" Duke of Brittany, and his wife transferred the honour of Abergavenny to Earl Miles in [1141/42].
The Gesta Stephani Regis records that "Paganus filius Joannis…et Milo" of Gloucester were killed, dated to [1137/40]. It is unclear why the two deaths are reported at the same time as a later passage in the Gesta records that "comes…Herefordiæ, Milo" was killed by arrow, and in a third passage that he was killed while hunting, dated from the context to [1142/43]. A manuscript in Aske’s collections names “Milo…Erle of Herforde, Lord of Bricone and of all the Forest of Done, and also Constable of England…” among those buried at Lanthony Priory. 3
