Legend has it that Joseph of Aramathea took the Holy Grail and Mary Magdalene to France. The Magdalene was said to have been married to the Christ, and the Holy Grail is said to symbolise their blood line, rather than being a physical object.
I now have firm evidence that members of Jesus' family did indeed make it to France, in order to found a cornichon preserving business.
Charles Christ, part of the SOCIETE CHRIST (web address www.christ.fr) is a family business. The business motto is "de père en fils" or "from father to son". I rest my case.
