Whatta ya know there is a 'Society of Daughters of Holland Dames'. & They are in the business of preserving and promoting the historical legacy of the 17th Century dutch settlers from the Netherlands.
For example they remind us with a plack on 2nd Ave. and 13th Street that the Stuyvesant pear tree once stood there. When the 1811 street grid covered over Stuyvesant Bouwerie and most of its vegetation there was one tree left. Poor creature was the victim of a vehicular accident. Two wagons crashed into each other and one went into the tree knocking it down. That was in 1867. Standing on a NYC street corner was just as dangerous then.
The word plack meant a small scottish coin in the 14th -15th centuries. The Scots borrowed the word from the Flemish placke ... meaning a small coin.
