Most of the top of this tree is from Geneanet family trees combined together. There are some Geneanet trees that had Thiebault as 2 separate Thiebault brothers, some that had Jean and Thiebault as the same person, and some the had Thiebault and Jean as 2 people. I thought it made the most sense, based on dates of death and the document the said 'Thiebault died during the Galas' ,that they were brothers.
