Karl Johan Johansson

I am looking for Karl Johan Johansson, b 13.10.1820, his wife Maria Kristina Svensdotter, b 27.11.1825 their two sons Sven Johan, b 7.11.1848 and Johannes b 6.5.1852. They lived in Växjö parish, Småland. Emigration to North America annotated in Växjö registers 25.5.1853 (not departure day) Also recorded in the passport registers for 1853. I have not found them on any ship. I thought maybe they left from Norway. Thanks for any help you can give me or any suggestion to help me. Martha Johnson
