Hi,
I don't know anything about the Gillis' - just that that name married into our family a couple of generations back. My active research is temporarily on hold as I have returned to school full time. However, I do follow up on whatever "falls into my lap" and I just happen to be going to visit my grandmother for a few days at the end of the week - she is the source of this Gillis info. I'll take a copy of your posting with me and see what it triggers for her and get back to you.
Cheers,
Joanna
