Pity, anyway as I am in Belgium and will start search on some Lienard's , for a friend of mine...
Is there anything you need to know on those families ? I will certainly come across lots of them.
By the way , the name Cuvelier meant a barrell maker.
Brasseur in modern french is someone that makes beer but before it was someone working with their arms.( bras in french ) Someone making beer was a cambier , also a common name over here.
All of this not of great interest but still...
