Jan Pietersz Graeff

[2] It is uncertain which one was the first Graeff active in Amsterdam [Pieter or Jan].

[3] Jans mother was Griet Pietersdr Berents[4] descendant from Wouter Berensz and his wife Dieuwer Willemsz de Grebber, called Berents, of the De Grebber family, baljuws of the Waterland,[5][6] and Willem Eggert, stadtholder of Holland.

[7] Jan Pietersz Graeff married to Stein Braseman and had five sons who survived their childhood:[8] Jan Pietersz Graeff lived in a house on Damrak, called Huis De Keyser, which was owned by his descendants for centuries.

His sons Lenaert, Dirk and Jacob ran a hardware store in the house called De Keyzershoed (Huis de Keyser) in the Niezel street, where the Imperial Crown later hung.

When he wanted to establish himself as a trader in North Brabant, his sons intervened to return him to Amsterdam soon.
