Samuel Leth Ships Carpenter

Thanks to some very helpful information from this website I've uncovered valuable information about my Norwegian Ancestors but have failed to throw any light on the circumstances surrounding the death of my Great Great Grandfather Samuel Nicholas Leth the Ships carpenter and son of Hans Helmer Leth. Samuel didn't come to Australia but apparently died between 1856 when his daughter Juliane Marie was born and the 1865 Census at Ostre Moland which shows his wife as a widow with sons Jens, Hans and Jorgen. Curiosly Juliane is missing. One of the birth records shows his full name as SAMUEL NIKOLAI HANSEN LOTH VASMEKROGEN STROMSBOE. What do the last 2 names mean. Are they to do with his address or maybe his profession. How, where and when Samuel died seems to be a mystery can anyone throw any light on this for me?
