Whitaker’s grandfather, one of the leading Wiltshire clothiers of his day, received a grant of arms in 1561. His father sat for Westbury in 1586, but settled in Plymouth after marrying into the town’s most celebrated seafaring family.
Whitaker was returned for the borough to the final Jacobean and first two Caroline Parliaments, probably as a nominee of the 3rd earl of Pembroke. His parliamentary career coincided with that of Laurence Whitaker, but he was clearly the less active Member of the two. In 1624 he was appointed to consider bills to define copyholders’ rights on a Dorset manor belonging to the chapter of Salisbury (13 Apr.) and to relieve artisan clothworkers in London (15 Apr.), and is known to have attended both committees. He was probably also the Mr. Whitaker who was named on 3 Mar. to help draft a bill against abuse of habeas corpus, and was added to the committee for Lady Bulkeley’s estate bill on 4 May.
During the 1625 Parliament Whitaker was named to the legislative committee concerned with Sabbath observance (22 June). It may also have been this Member to whom the simony bill was entrusted on 2 August.
Whitaker was appointed recorder of Shaftesbury in 1627, but surprisingly did not secure re-election to the next Parliament. He had possibly lost local support through his prominent role in the enclosure of Gillingham forest.
