Need assistance finding Jonckheere's in France(Paris & Coastal area)
My grandmother; Maria Magdalena Jonckheere had an older brother named Arthur Henri Jonckheere born 4 April 1888 in Westkerke, Belgium.
During WWI he moved to the Paris, France area and married a woman named Louise.They had two children there; Marthe and Leon.This family supposedly owned a very respected snail factory andor restaurant.When Leon was old enough he ran the factory andor restaurant.
He later sold it and moved to the coast, possibly in or near Normandy.
Marthe Jonckheere was married in 1940 and we were told she died in 1940.I do not know the name of her husband or if she ever had any children.
I do not know if Leon married or had children but I would assume he did.Marthe and Leon were both born in Staines, Saint-Denis, Seine-St-Denis, Ile-de-France, France.
Any assistance in finding this lost branch of my family would be greatly appreciated.
