Hervey od MD
In 1657, George Beckwith, Gent., became involved in administration of the estate and married the young heiress. Mr. Beckwith rebuilt the small house into a grand English manor which is said to have survived for over 200 years.

George Beckwith is thought to be of the Beckwith family originating in Yorkshire, England. He emigrated to Maryland in 1648 as an apprentice to Thomas Hatton, Secretary of State for Maryland. He was a Protestant. He served his apprenticeship and then went back to England for a short time. By 1657 he returned to Maryland, bringing with him several transportees. He was married by October 3, 1657 to Frances Hervey, orphan and heiress of Nicholas Hervey and thereby gained rights to St. Joseph manor.

George Beckwith maintained an inn and a ferry at St. Joseph's. He served in some minor public capacities, such as coroner and overseer of the public roads.

Beckwith died at London, England, before his wife, Frances (Hervey) Beckwith, who died April 19, 1676. The estate was administered in Maryland by John Halls and later by Cuthbert Fenwick, Esq. and still later by Thomas Banks. The plantation was considered to be among the wealthiest in America at the time of the appraisal.
