You don't give a lot of information but I think I found the right family.
The Adriaan Lamper I found went to the USA in 1900. I couldn't find him on a passengerslist ( he went before his family) but his wife Anna Lamper-Hartoog and 6 children Abram (= Abraham ), Adriaan, Cornelis, Pieternella, and the twins Anna and Maatje left Rotterdam on the 2nd Aug 1900 and arrived in New York the 12 Aug 1900 on the SS Statendam. They went to Adriaan ,already living in Grand Rapids. ( Source www.ellisisland.org )
On www.zeeuwengezocht.nl you can find the marriage of Adriaan and Anna and lots more like the date of births of the childeren etc.
Have alook also on www.genver.nl. Using this site you can find the records on Familysearch.com
