The first Comtois (well, he was a Gilbert or Gillebert dit Comtois)
Here is the first evidence of Louis Gilbert dit Comtois in Quebec City. He was sick at the Hotel Dieu in QC on December 31, 1717. The record is just past 1/2 way down the page. He is listed as 19 years old and a member of M. Ameriton's company (in the Troupe de la Marine). It looks like he is called "Eloy" - maybe a nickname and says he is from Besancon in Franche Comte.
