I'm not sure what to make of the reference to cat house boats in the Holland Netherlands article. Does that mean house-boats inhabited by cats or boats that also function as cat-houses? It's Amsterdam, so either one of those is equally likely.
Thanks for sharing, Brian. This list of articles looked familiar to me because I had seen the same list in my "Weekly Genealogist" email from NEHGS.
