Other land held by the de Birminghams does not appear to have been signed over to Dudley and there are records of the de Birmingham's ownership of it after 1527, e.g., Shutford, Oxon in 1544 which mentions a young William, son of Henry, son of William & Margaret de Birmingham.
However, this too appears to have been transferred away from them by Henry VIII, possibly under the advice of John Dudley, who was not executed until 1553.
