Immigration ship, Elling Pedersen Enger

I have recently acquired a copy of a page in my great-grandfather's Bible, handwritten by him, Elling Pedersen Enger of Eggedal, Norway. The copy is faint, but it reads: (Left Norway) der 20 April, 1854, ----til America der 20 Juni. I have not located a ship with those exact dates. 7 years later his parents came through Quebec so Elling may have also, but don't know for sure. Is there a way to find out the ship name from those dates? Dianne Snell
