Whithed’s ancestors had held the Hampshire manor of Norman Court since 1433, but had not previously sat in Parliament.
Returned for Winchester at the next election, probably with the support of his colleague Sir Richard Tichborne*, Whithed’s numerous appointments included the committee for privileges (9 Feb. 1626) and a committee to consider matters of religion (10 February).
Following the dissolution, Whithed was commended by Tichborne for his diligence in collecting the Forced Loan in Hampshire.
During the summer Whithed and Tichborne were praised by Conway for their pains in billeting soldiers.
