David Cyr is my G-G-G-Grandfather. I too have amassed a lot of information on the family and have traced all lines from David (paternal and maternal back to the 1600's)BUT would love to check/share information. Zepherin and Philomene Bourgeois Cyr are my G-G Grandparents also (Lineage through their son George and grandson Loren). To which Zepherin offspring does your Louise belong? I also have some limited information on David and Emily's children and have traveled to Kankakee Co, ILL and met a Great grandson of Romain. I believe that I have also located some of Narcisse (Nelson's) descendents. Anyway would love to share info.
