Atte Mille’s early life remains obscure, although he may possibly have been the son of the Robert atte Mille who, in May 1367, was serving as under sheriff of Sussex. He certainly had kinsmen in that county, for in 1381 Richard and Joan atte Mille of Waldron granted him a messuage and 30 acres of land which they had previously held there. Most of his property lay within a few miles’ radius of Guildford, however, and in February 1385 he was called upon to witness certain transactions of Thomas Holand, earl of Kent, and Robert Wyvil, bishop of Salisbury, in the nearby vills of Godalming and Artington. In the following year he offered sureties in Chancery for Hugh Roger, then a prisoner in London; and at some point before June 1387 he was made a feoffee by Sir John St. Cler and his wife, Mary.
Atte Mille had meanwhile continued to live in Guildford; and in 1394 he was summoned to attend the assizes there as the defendant in an action of novel disseisin brought by William and Joan atte Well. He stood surety for a local man being sued for trespass in 1401, and witnessed a number of deeds drawn up in the Guildford area at the turn of the century. His decision to sell a messuage and eight acres of land in the borough to John Willersey in 1405 may perhaps have been forced on him by financial necessity, but this cannot now be proved. It is, indeed, by no means certain that he was permanently ruined because of his earlier misfortunes: he actually appears at about this time as lord of the manor of Hambledon, Surrey, with the right of presentation to the living. Atte Mille was still alive in February 1414, when he was again being sued at the Guildford assizes by William atte Well.
