AD 1590?-1890


For younger generations of ancestors who are descended from this family:
see page on Van Rossum

The known origins of this family are in Goedereede on the island of Goeree-Overflakkee, south-west of Rotterdam. The name means "cheap", and according to Leendert Dupper, the brother-in-law of our ancestor Cornelis Goekoop (1751-1815), it was derived from the nickname "goekoop sant" (cheap sand) that Jacob Jansz. apparently had as a builder of dams, etc. Further sources on the Goekoop and related families are the manuscript by Cornelis Goekoop himself (the original is still in the Goekoop family, a copy is in the "Centraal Bureau voor Genealogie" in The Hague) and the book "Het geslacht Goekoop" by M.G. Wildeman, 1914, based on Cornelis Goekoops manuscript.

Occupation: owner of the farm "Oostdam" near Goedereede (demolished around 1830), and "gesubstitueerd strandvonder". In the early morning of Wednesday, January 31th, 1691, a very cold an foggy winter's day, Corstiaen received some unexpected visitors. They were "Koning-Stadhouder" Prince Willem III of Orange (= King William III of England), Hans Willem Bentinck (the Earl of Portland), a number of other dignitaries, and seven sailors. King William, returning by boat from England, had planned to arrive in Hellevoetsluis, but this had proved impossible because of heavy fog and fields of floating ice. He had then tried to reach the shore in an open rowing boat, which only succeeded after 23 hours. The visitors were then brought to Corstiaen's farm Oostdam, where they were warmed up again by the fire which was lit for them, and were given an English breakfast. As soon as the fog had lifted, they went back into their rowing boat in order to get to the mainland. William arrived in The Hague that evening with a severe cold. Corstiaen was rewarded for his hospitality with a silver tobacco box.

Occupation: "schepen", "burgemeester-thesorier" and "president" of Goedereede. There are probably many family links between all the Boogertmans that we have come across in our tree, but at the moment these links are not yet completely clear. Christiaan's wife Angenietje Boogertman was probably related to Aren Claesz. Boogertman, the second husband of our ancestor Aechje Adriaens Zuyderwerff; to Cornelis Arensz.

Occupation: Adriaan Goekoop was not trained as an engineer, but eventually he rose to "Inspecteur van de Waterstaat", with "Rijkswaterstaat", the large government organisation responsible for building and maintaining the main roads, waterways, and dikes in the Netherlands. In his period "Waterstaat" also built many churches. He started as an "assistent-opzichter" on Goeree-Overflakkee, and rose quickly through the ranks under Jan Blanken, the Inspector-General. In 1847 he had become not only "Inspecteur" of his own district, but also acting head of the other three districts. However, it was felt that he could not succeed as Inspector-General, because he did not have an academic degree. Still he became head of "het Corps van Ingenieurs van de Waterstaat", which he remained until he was over 80 years of age, and was "corresponderend lid" of the "Koninklijke Academie van Wetenschappen". He was appointed "Staatsraad in buitengewone dienst" and "Ridder in de Orde van de Nederlandse Leeuw" for his services.

3. Diederika Maria Goekoop

Diederika and her husband were related through their common grandfather Cornelis Goekoop, 1751-1815. The younger Cornelis, descended from his grandfather's first wife Anna Maria Ketelaar, was "burgemeester" of Goedereede, Ouddorp and Stellendam, and later contributed greatly to the expansion of The Hague by buying and selling pieces of land, which also made him very wealthy. He was the guardian of his sister-in-law Louise's children after she, our second great-grandmother, had died at the age of 39.
Cornelis Goekoop owned the estate "Sorghvliet" in The Hague, and lived there in the monumental house called "Het Catshuis". In 1961 the estate was sold to the Dutch government, and since then "Het Catshuis" became the official residence of the Dutch Prime Ministers. The address is Adriaan Goekooplaan 10. This street was not named after our third great-grandfather Adrianus Goekoop, but after Adriaan Eliza Goekoop (1859-1914), the son of Cornelis and Diederika Maria Goekoop.
