Sondes’s family originated near Dorking, in Surrey, and acquired Throwley by marriage in the 1470s.
Returned to his sixth Parliament in 1604, Sondes received only six committee appointments over all the sessions. On 28 Mar. 1604 he was one of those Members who accompanied the Speaker to explain to the king the proceedings of the Commons over the Buckinghamshire election case. He was subsequently named to the committee for a private bill to allow John Theobolds, a Kent man, to sell land to pay his debts (22 May 1604).
In the third session Sondes was ordered to attend the conference of 25 Nov. 1606 with the Lords on Union with Scotland.
