I am not too well informed on Jessée Barbeau but on Michel Lemire I have much more information about him in my own little family tree which you can consult following details below:
http://rodriguelemire.tripod.com/rodrigue.htm Click on Ma généalogie - Family tree
Once Geneanet is opened select your working language (clicking the proper flag)
If you wish to see more details plse send me a note
The family tree is now ready for consultation
Also you can look at the Lemire's association web site (under construction) for more information about the Lemire in general
