The History of the Several Towns, Manors, and Patents of the County of Westchester (1881 revised edition, Vol. I)
Cornelius Beeckman, (who married Christiana Huygens of Cologne, who died December 4, 1506,) flourished about 1478; his son Gerard, born at Cologne on the 17 th of May, 1558, married Agnes Stuning of Cleves, (born January 13, 1557,) studied divinity at Frankendoel, 1576, 1577 and 1578, and was conversant with the Latin, French, Italian and German languages ; after completing his education he traveled extensively through Europe. During the great religious persecution, which commenced about this time, (161 2,) several delegates were selected to meet the Duke of New Berg, the elector of Brandenburg at Berlin, and King James of England -- whom the Protestant world flatteringly denominated " Protector de la Fois" (Protector of the Faith) to obtain assistance in behalf of the reformed religion. Gerard Beeckman and Velt Keyser, a gentleman of inferior abilities, were chosen for this important mission, which J:hey executed with so much credit to themselves that King James caused the coat of arms of the Beeckman family to be remodelled, as it now is, viz : "a rose on either side of a running brook." After the death of his wife at Mulheim, on the 10th of March, 16 14, he became auditor and secretary of the electoral chamber at Cleves, in the service of the Elector of Bradenburgh. He died at Emeric on the 31st of January, 1625, aetat 66. His eldest son was Hendrick or Henry Beeckman, who was born at Cologne, Sept. 14, 1585; fled from Emeric and settled at Berg. He married for his second wife, Mary, daughter of Wilhelmus Bandetius, minister of the Reformed church at Tutphen Guilderland; she was born January 24, 1621, and died the 17th of September, 1631. Hendrick Beeckman died at Wezel, Dec. 2, 1642. Their son, William Beeckman, was born at Hasselt, Overyssel, April 18th, 1623.
