Questions for two of the last Jews alive that were born in Dorsten

Hello , My name is Max Morgan . My grandfather Alfred Perlstein and his sister Laura Whiteman( nee Perlstein ) were both born in Dorsten (1922 and 1924 respectively) and left with there parents in 1936 . They both have relatively clear memories of growing up there . If anyone has a question about the town I could ask either of them .
