I just learned today that Jacob's sister Tryntje - born in 1836 - also emigrated to Grand Rapids, MIchigan with her husband Klaas VanderVeen (married 12-Apr-1862) in 1866 aboard the Duisburg.  No doubt, the decision to emigrate was made easier by the fact that Tryntje had an elder brother here in Grand Rapids. 

I have photos of Tryntje but want permission from the owner of the photos prior to my posting. 

Interesting note: Klaas worked at a sawmill in 1880.  Did he and Jacob work together?
