Hi Colleen,

Try this website: http://goo.gl/0AtzZ (I shortened the url)

Go to "eerste persoon" and type Lefebre in box achternaam
omit tussenvoegsel and type Wilhelmus Johannes in box voornaam
zoekwijze: klinkt als
scroll down and click "zoeken"

This will give you 15 results.
Click on one of the results and you see "inzien akte"
A new will open and you can access and download the original certificate / register

This site will also search in the databases of the archives of Roosendaal and West Brabant when you use the "zoek ook in function" .

Good Luck,

Rian in the Netherlands
