In the 1912 work "HOLLANDERS OF IOWA" by JACOB VAN DER ZEE, that can be found online at:
http://www.rootsweb.com/~iasioux/books/hollanders/introducti...Van Der Zee relates, in Chapter 15, that about 800 immigrants from The Netherlands came to Marion Co. in 1847 and that another group of 250 followed in 1849.
Does anyone know if a lists of these immigrants have been published? If so, where can they be found?
