A very old-fashioned Flemish name: Veerle. One of the few bad-ass girl names in the Dutch language. It is derived from medieval times, when ‘Veerlen’ were travelling warrior women. I do happen to know several men named Fons, some even younger than me. I even know a man named Wies (his full name is Aloysius).
Maybe ‘Wies’ was short for ‘Louise’?
