Waltham’s father was probably a merchant who began his career at Exeter, Devon, but then settled at Weymouth, where he served three times as mayor.
Waltham sat for Weymouth in the 1628-9 Parliament. Although he left no mark on the records of either session, he was instructed by the corporation in May 1628 to petition the Privy Council for a supply of powder and shot to bolster the borough’s defences.
With his normal mercantile ventures disrupted by war, Waltham turned to privateering, securing letters of marque in 1627 and 1630 for ships of 100 and 140 tons respectively.
Waltham’s wife, a sister of Denis Bond†, died early in the Civil War. His own date of death is unknown, and no will or administration grant has been found. He was certainly dead by 29 Jan. 1647, when his son Henry was admitted to the freedom of the borough in his stead. Henry, who had taken up arms for Parliament, sat for Weymouth in the 1660 Convention.
