[1][2][3] The eldest son of William Codd (d. 1652) of Watringbury Parish in Kent, England and his wife Mary St.
She had died by 1679, when Codd married Anna, the widow of Theodorick Bland of Westover, a major planter and politician who had served as speaker of the House of Burgesses.
He acquired a plantation near the border between Northumberland and Lancaster Counties on a branch of the Corotoman River.
Although Codd was initially successful in that litigation, it dragged on, in part because in addition to trying to resolve her husband's estate, Sarah Bland also sought resolution for the death of her son Giles Bland, who was executed for his part in Bacon's Rebellion.
Codd also owed money to Jamestown merchant William Sherwood, Nicholas Spencer and John Strechley.
By 1688, Codd moved his family further north along the coast, to Cecil County, which he represented first in the lower house of the Maryland General Assembly in 1692, then in 1694-1697 and finally in 1701–1704.
