Sir William Portman had acquired land in Marylebone, London, which through the later housing developments of Henry William Portman became the Portman Estate, which today is one of Central London's largest landlords and is still the basis of the wealth of the Portman family.

The family estates passed under a settlement to Henry Seymour, fifth son of Sir Edward Seymour, 3rd Baronet, of Berry Pomeroy and Anne, the second daughter of Sir John Portman, 1st Baronet.
