Thingvalla Passenger List (seeking Fred Nelson)

I'm searching for the passenger list of the "Thingvalla", which I'm hoping will include my great-great-grandfather, Fred Nelson (his last name could have been spelled a variety of ways). His naturalization papers include the following (all as spelled on the papers): Name: Fred Nelson b. July 1, 1868, Ystad, Sweden Occupation: Shoemaker Emigrated from: Malmo, Sweden, Aug 2, 1888 Ship: Tingwalla On this website I was able to track down the "Thingvalla", which I'm assuming is the same ship. Especially since it departed from Malmo on August 2, 1888. However, this ship collided with the Geiser. I was able to find the passenger list for the Geiser, but not the Thingvalla. Can anyone help? Thanks in advance. ~ Lee
