Hi! There is a very large number of JUBYs who derive from Dzubay - anglicised to JUBY - who live in the States. It took me a long time to distinguish these descendants from the ones who settled from England. These latter, in turn, used to be called de Huby (from their main manor in Leicestershire) and moved to the Norfolk/Suffolk border around 1350. Try saying de Huby in the local accent and you get a "J"
