Messager lived at Fisherton Anger on the outskirts of Salisbury and not far from Old Sarum, the deserted borough which he represented in three Parliaments. Occasionally a witness to deeds sealed at Fisherton, he also did likewise at East Harnham, near-by.
Some idea of Messager’s status is given by his appearance as an attestor of the county elections held at Wilton for the Parliament of 1415. His occupation is not recorded, although it would seem that he received training in the law, for in 1421 he was named as an attorney to receive seisin of the manor of East Harnham and estates in Buckinghamshire from the son and heir of Sir Laurence Lynford, and he took on briefs at the assizes held at Salisbury in the years 1422-4.
On occasion Messager was placed in positions of trust, notably as a feoffee of the manor of Ugford St. James near Wilton, which came to John Giles* jure uxoris, and of property in Salisbury,
