This area remained largely untouched by the Grosvenors until the 1720s, when they developed the northern part, now known as Mayfair, around Grosvenor Square. Mary had inherited the manor of Ebury, 500 acres of land north of the Thames to the west of the City of London. The history of the Grosvenor Estate begins in 1677, with the marriage of heiress Mary Davies to Sir Thomas Grosvenor, 3rd Baronet (1655–1700). Its sectors include residential, office, retail, industrial, along with hotels. It has four regional development and investment businesses (Britain and Ireland, the Americas, Europe, and Asia Pacific) and a portfolio of indirect investments. It has a global reach, now in 62 international cities, with offices in 14 of them, operated on behalf of its owners, the Duke of Westminster and his family.
