We took the overnight ferry to Stockholm and then a train down south. Växjö is a wonderful small town - sort of a cross between Dexter and Ann Arbor - and most bizarrely, we ended up staying in a hotel that was sited exactly where my grandfather lived until emigrating to Canada at age 4.5! My great grandfather was a foreman at a match company that housed its employees too. It was torn down in 1926 and later our hotel was built on the same location. We were able to go as far back as the 1820s in the one day spent at the institute, learning that my great-great grandfather was a wall-builder/bricklayer - working independently; my other great-great grandfather made rope for the navy in Karlskrona, in the longest wood building in Sweden, which still stands. We found out my grandfather Gunnar was born with a different name - Uno - and probably renamed as a tribute to a brother who died young, and that threw off the research for a short while. And Claire had the insight to ask about the ship register at the end of our long day, when I was getting overwhelmed with details, and we found it.
