Though his father was chief justice of the Anglesey circuit, it was probably Eure’s stepmother whose influence secured his return to the third Jacobean Parliament for Beaumaris. Her grandfather, Sir William Maurice*, initially agreed to support (Sir) Richard Wynn* in the Caernarvonshire election of December 1620, but Lady Eure canvassed him vigorously on behalf of John Griffith III* of Llŷn, a relative of her first husband, John Owen†. In return, Griffith’s supporter and uncle (Sir) William Jones I*, whose ambitions were now focused on acquiring an English judgeship, stood down at Beaumaris in favour of Eure, who left no trace upon the records of the 1621 Parliament.
Appointed attorney-general of the Council in the Marches in 1622, Eure clearly prospered, paying £3,450 to (Sir) William Croft* for an estate at Gatley Park, Herefordshire in 1632.
Eure finally secured the post of king’s serjeant in 1640. He was also returned to the Long Parliament for Leominster, but failed to avert the abolition of the Council in the Marches in 1641. Named as a commissioner of array at the outbreak of the Civil War, he did not serve, and was not expelled from the Commons until named as Speaker of the royalist Parliament at Oxford in January 1644.
