Brereton’s marriage to Margaret Savage united two of the leading Cheshire gentry families. When Brereton constructed his magnificent pile he based the design upon his father-in-law’s house, Rock Savage.
At the opening of the 1614 Parliament Brereton was named to both the privileges and expiring laws committees (8 April).
On 6 Feb. 1621 Brereton offered four bills to the Commons, which he formally presented two days later. However, the subject of these measures is uncertain as both the Commons Journal and the ‘X’ diary give different titles for all four.
Brereton obtained an Irish barony in 1624, probably by paying the standard rate of £1,500, but he remained active in Cheshire affairs until his death.
