The origin of the name De Bie:

In "Limburgs Tijdschrift voor Genealogie", 1992 no.2 is an article about French family names in Limburg. Under the heading "Families waarvan de geografische herkomst bekend is" is written under the item "Debye":

Debye (de By, de Bye, de Bije, Debeij, Debeije, Debie, Debije).- the farmers family Debye is already in the 17th century living in the present Zuid-Limburg. The fame of prof. Pie Debye, Nobel price 1936 for physics, was reason for some genealogical research into his family. As far as I know there is no known connection yet with the French speaking Belgium (Walonië), but it seems reasonable to suppose that this family derives her name from the hamlet By near Charneux. The name Deby is already in use there in the 16th century. The name is carried in 1591 by a "Thyry de By soub Charneux".
