Passengerlist Quebec, Canada 1847 - death records Buffalo, NY

I look for a passenger list from Bremen/Bremerhaven to Quebec, Canada, in the spring 1847.
I search the Johann Heinrich Fangmann family of Steinfeld, with parents and two child. On the same ship should be Anton Kirchhoff and Anna Maria Meyer.
On the trip from Quebec to New Vienna, Iowa died the mother Maria Catharina Fangmann(Meyer) and the son Franz Henrich Fangmann in Buffalo, NY 1847.

Have any one an idea to find the passenger list and the death records in Buffalo, NY?

Have a nice Christmas time,
