Bagehott came of a minor gentry family which claimed to have resided in Prestbury, Gloucestershire, since the fourteenth century, initially as tenants of Llanthony priory.
Bagehott was first elected for Stockbridge in 1625. He had lodgings in Southampton, and his various connections within Hampshire, such as his friendship with Sir William Uvedale*, could have facilitated his return.
Bagehott remained on close terms with Hay, now earl of Carlisle, for whom he seems to have had a fatherly affection.
