There are instances where there is an abreviation n. which at the end of my Bygdebok says n. neutrum What does neutrum mean? In a couple of instances that I am looking at now the n. preceeds a year. Also, I am confused when I read 2 1/2 hud 1/2 hud or 1 1/2 kvernhus. How can you have 1/2 hud or 1 1/2 grinding mill? Dave
