de Biecourt ...new info...
i have located a site on the French web( which came up on a search using GOOD SEARCH [my s. engine], named "genealogie des familles VERNEZ, LEJEUNE,DELMOTTE,QUEVAL".The site includes a number of "De Biencourt" names from the 15th c.,and contains a De Biencourt related to a Jean Maupin! i am rather new to genealogy, so if any of you might be interested, i tho't this could help us.
i stumbled upon this site . having studied 4 yrs. of French, it became clear to me that our "de biecourt" was not a correct french word. so i tried De Biencourt, meaning, from the good(or great) court,and the referenced site popped up.
hope this info may be of some help in your searches for our 16th century Maupin lines.
