I forgot to speak about the names as Mr. Claes doens't give suffiscient information to you. Generally the person is called under their first name, but in the first part of XX century in the campaigns the farmers were called with their second name very much times.
People can have one name, 2, 3 4, or more for the nobility. Personally I hav 4 names, the first, Philippe, is the one everybody is calling me, the second is the name of mother's father third is the one of father's father and last one, Ghislain, is given to protect for certain ills. That it is because I am the first boy, I had 2 broters ad after a sister. This sister had names like me with mother's mother and father's mother name, and Ghislaine after.
My brothers had like it was so in the past too the names of their godfather/godmother and i final "Joseph" and spemtimes "Josèphe" for the women Joseph is an allusion to St. Joseph (19 March) but I think that the St. Joseph has not the same importance in other religions than catholics. You understand.
