M. Joanne,
The Austrian period in our country was from 1715 to 1794. For that period (and later) we have baptism registers and marriage registers, made by the (Roman-catholic) parish priests.
On the internet I found a (flemish) local association for local history (translated): 'The Old Land of Edingen', for short: 'Holveo'.
See http:/users.telenet.be/HOLVEO The vice-chairman is mister Michel MATTHIJS michmatt@skynet.be .
That's all I can do for you (my poor school english!).
