I think I have found more on William. That is, if your grandfather Joseph was born around 1924 and dad William was married to a Dina....
If so, I traced William back through the various censuses:
1940: William Vanderwyst, Little Chute, est. birth year 1880
1930: Wm Vanderwyst, Little Chute, est. birth year 1880
1920: William Vanderweist, Outagamie, est. birth year 1878
Wife in all these 3 censuses was Dina(h).
1910: William Vanderweyest, Mayhew Lake, Benton, Minnesota, est. birth year 1878
He is living with his brother John and his family , and his parents Frank (66 yrs) and Hendrid (69yrs).
1900: No William to be found, but the parents:
Frank Vanderwyst, Little Chute, 55 yrs, born Feb 1845
Harriet Vanderwyst, 59 yrs, born Feb. 1841
Est. year of marriage 1873
And a son, Peter, born May 1874
So now we have the names of William's parents, Frank and Hendrid/Harriet and 2 brothers; John and Peter
In all the censuses the est. immigration year is between 1889 and 1891
So far for the US side, now the passage...
And luckily there they are ( www.castlegarden.org
Ship Veendam, dep. Rotterdam, arr. 09 Apr 1891
Vanderwijst, Hendrina, female, 49 yrs
Vanderwijst, Frans, male, 46
Vanderwijst, Petrus, male, 15
Vanderwijst, Hendrik, male, 13
Vanderwijst, Johannes, male, 11
Vanderwijst, Willem, male, 8
The ages mentioned on early passenger records are often not very accurate, so the difference between the actual age and the mentioned age is not unusual....
At least the approximate names are known now.
From thereon the Dutch details are easy to find in this case on http://www.bhic.nl/index.php?id=10004
also with English interface. I put them together for you (US names are between brackets).
