When Lambert came from the Netherlands before 1644 he purchased on the Southern tip of Manhatten Isle 50 acres which included the site where the Empire State Bldg. now stands. About 1656 he sold the property to the Roosevelts and moved his family to Ft. Orange, Albany, NY where he owned a home at the corner of Green and Beaver St.

Lambert Jochemse Van Valkenburg of Valkenburg on the Guele River, seven miles east of Maaestrict, Limburg Province of the Netherlands, obtained a marriage license in 1642 and married Annetje Jacobs. This license, as furnished and translated by “The Centraul Bureau voor Genealogie” of The Hague, The Netherlands, reads as follows:
“Appeared (before the marriage council of Amsterdam) as before (on the 4th of January, 1642) Lambert Van Valckenburgh, from Millen, 26 years old, having no parents (anymore) living on the Boomstraat, and Annatje Jacobs, from Tonningen (Schleswig Holstein) living as before, having no parents, 20 years old, requesting to have their three Sundays’ banns procalimed, in order to have their marriage solemnized and celebrated, insofar no legal impediments occur. And after their having declared to be free persons and (not) related to each other in blood, which would prevent a Christian marriage, their banns have been granted.”
This translation of the banns of marriage for the common ancestor of all the Van Valkenburgs in America was furnished to The National Association of the Van Valkenburg Family in America by Dr. Kenneth L. Marsi of Long Beach, California, who obtained it directly from The Netherlands.
