Anketill belonged to a junior branch of a prominent family settled in Dorset since Domesday which had represented Shaftesbury several times in the fourteenth century.
It was evidently through Tuchet, who became 2nd earl of Castlehaven in 1617, that in 1621 Anketill secured a parliamentary seat for Hindon, the nearest borough to Fonthill Gifford. Hindon had largely been controlled by Sir James Mervyn since 1585, and after Mervyn’s death in 1611 his estate and influence at Fonthill Gifford passed to the Tuchets. Anketill must also have enjoyed the support of south-west Wiltshire’s principal landowner, (Sir) Thomas Thynne*, who had married one of Castlehaven’s sisters.
Castlehaven was openly Catholic by the early 1620s: he was presented to the House of Commons as a recusant in 1624, his Fonthill Gifford house was regularly searched for arms, at least two of his servants were Catholics brought over from his Irish estates, and his second son became a Benedictine monk.
Anketill accompanied Castlehaven to Ireland in February 1627, the earl having been sent there with a royal commission to raise money.
Anketill died at Newmarket on 12 Apr. 1638 and was buried in the church there six days later.
