I found the above genealogy while doing some research at the Mormon Library in Salt Lake City. My mother's grandfather was a Sirard from Québec and I have made contact with two others in Québec and one in France who share the name. I wanted to purchase copies of the genealogy as gifts but when I sent a letter to M. Gaston Dupuis at Le Centre De La Genealogie De Montréal, C. P. 724, Montréal, QC, H2L 4L5, Canada it was returned with the notation that the addressee was unknown. Another genealogy buff suggested I might contact M. Dupuis through this message board and it was in this way that I found your name. I hope that you will be able to advise me as to how I might obtain copies of the noted volume. Many thanks for you reply.
