I am trying to find information about my great-grandfather who immigrated from Denmark. Does anyone have any info on where to find ships arriving in New York in 1891? I have tried searching at CasteGarden and Ellis Island websites, but they do not cover March of 1891.

His name was (originally):
Nils Peter Edward Rosenkilde Rasmussen
From - Vaggelslovern, Falster Denmark

Was born on 12/1/1869
Entered the US on 3/17/1891
changed name 9/14/1900
(this info is from his name change papers)
He changed hiw name to Peter Edward Robinson.

Any help would be greatly appreciated. Thanks!
