Jan Abrahamsz Beerstraaten

Jan Abrahamsz Beerstraaten (bapt. 1 March 1622 in Amsterdam – buried in July 1666 in Amsterdam?) was a Dutch painter of marine art and landscapes, particularly of events of the First Anglo-Dutch War and Dutch-Swedish War.
Biography.
There is some confusion about the identity of four landscape painters named Beerstraaten; Johannes, this Jan Abrahamsz, Abraham, and Anthonie. Jan Abrahamsz, painter, married in Amsterdam on 30 August 1642. From this marriage eleven children were born, and when he married a second time in 1665, a daughter was born. Currently, The RKD records Johannes as the same person, and Abraham Beerstraaten is considered to be his oldest son.
Anthonie Beerstraaten was related to this painter. The RKD has registered two paintings signed Anthonie van Beerstraten: one is a view of a southern seaport from 1664 (currently location Enkhuizen) and the other a view of a church in Aarlanderveen in the former city hall of Alphen aan den Rijn. Based on these two paintings C. Hofstede de Groot an early Dutch art historian, classified paintings signed A. Beerstraaten as by Anthonie if they were a poorer grade than ones already attributed to Abraham.
