Quackenbosch family

Hello all... Is there anyone who is familiar with the genealogy of the Van Quackebosch family? There are some conflicts on Geni that I can't resolve. The data I find online seem inconsistent with what's written in a 1909 book 'The Quackenbush Family in Holland and America', written by Adriana Suydam Quackenbusch - and that may well be the reason for the conflict on Geni too. Thanks for any pointers!

Here the link to the book http://ia700508.us.archive.org/5/items/quackenbushfamil00andr/quack...
