My name is Mariska Hammerstein. I'm a Dutch writer in Amsterdam.

I'm reacting to you suggestion to send in examples of 'Dutch DNA in New York'.

Less than half a year ago a children's book I wrote on Peter Stuyvesant and New York/New Amsterdam was published (in Dutch). It's called Een ordeloze bende. (Meaning: A Disorderly Lot)
In the book I added several examples of names and words in New York (and surroundings) which have Dutch origines.

Pancakes = pannenkoeken
Cookie = koekje
Boss = baas
Spuyten Duyvil = In spite of the devil (famous legend)

And there are all kinds of names that have been translated from Dutch (you already mentioned Wall Street):
Harlem = Haarlem (Dutch city)
Broadway = Brede Weg
Coney Island = Konijnen Eiland [Rabbits Island]
Governor's Island = Gouverneurs Eiland
Staten Island = Staten Eiland
Gravesend = Gravesande (Dutch city)
Hampstead = Heemstede (Dutch city)
Flushing = Vlissingen (Dutch city)
Bowery Street = after the "Bouwerij" [farm] of Peter Stuyvesant
Long Island = Lange Eiland
Stone Street = Steenstraat [The first dirt street in New Amsterdam that got paved; before it was paved with cobblestones it was called Brouwerstraat, whih means Brewer Street]
Marketfield Street = after the Dutch Marckveldt [the marketplace]
Maiden Lane = het Maagdenpaatje (the path the Dutch maids took to go an do the laundry in the open air)

Sincerely,
Mariska Hammerstein
