Lambert Van Valkenburg A New Netherland Ancestor

Lambert Van Valkenburg married Annetje Jacobs on April 4, 1642 in Amsterdam.

His name was recorded as Lambert van Valckenburgh, his bride as Annetje Jacobs. [Source: DTB 457, p.146]
 
He sailed to the New World before 1644 and settled on what is now the site of the Empire State Building in New York.

Many genealogists are not sure where or how they can find more information on an ancestor in New Netherland (present day New York) but there are many resources available, both online and off.

For example here is a document which I found online for Lambert.
