shipping logs: Luxembourgian emigrants to America

[scott]

Hallo,

I understand that from 1846 to 1860, the majority of emigrants from Luxembourg came through the travel offices of the Derulle-Wigreux and Sons in Luxembourg. Are these shipping logs accessible online?

Also, what about the years before 1846?

Finally, what would be the likely route of travel to board a ship (and likely harbor, Antwerp?) to America if one lived in Medernach, Diekirche?

Thanks!
