I went on to to search and find what are probably the pertinent Microfilms to look up.
They may have to be requested first if they are not on site.
If no one else has yet, when I go to the LAC next, I will look into it.
I say, "look into it" because I don't know how findable one person is in the microfilms.
Also, I don't know when I will go to the LAC, could be days or weeks...?
