Emmigrant Ships

How would I go about finding the ship my grandfather Henry Henriksen came over on from Norway? He was born 1879 and died in USA 1914 a young man of 34 years old. He married and had 4 children and came from Stavanger, Ogna, Egersund, Norway. I am assuming he came here around the years 1898 - 1901. I am interested in finding the port he left from and the port he came to. He lived and died in Philadelphia, Pa. Katiejanda - [email hidden] Catherine E. Maxin
