I know we’re the marriage took place NIVELLES but not year. The marriage was between Henri George’s Laurent Marie Ghislain Libert (born 1908) and Maria Rachel Anais Philippart (born 1910) Henri Libert died 1942. Taking into account there birth years I’m assuming they married around the 1930s ?
Ps: the only other thing I know they did have a child “Monique” which I assume was born prior Henri’s death.
