Fleurbaix, contrats de mariage passes devant matres Daniel Quyjue, Jean Defache et Pierre Delesalle, notaires a Fleurbaix 1567-1675, by Dalenne, Bernard and Selosse, C. R. Published by Wambrechies, France: Groupement genealogique de la region du Nord, 1990.
The only copy I know about is in the Familysearch library at Salt Lake City.
Among other records, I wonder whether there is a marriage record in Fleurbaix in about 1645, for Anthoine le Fevre and Anthoinette Vilain. They were the parents of Magdeleine le Fevre (le_Fevre-4, based on her marriage record in Mannheim in 1672) and possibly also the parents of Antoine le Fevre (born in Fleurbaix about 1647, died in Wallmow, Brandenburg, Germany on 1717, age 70) and/or Pierre le Fevre of South Africa (le_Febre-84).
Would anyone possibly have a copy and be willing to do a couple of lookups?
