I just found your message by accident. I thought I would be notified when someone replied to my messages.
I attached a photo of James Meek (1777-1834) homestead. It is SW of St. Thomas. Nearby, his son Thomas Meek built a beautiful stone house that I can't find the photo for. It is possible that Stewart (Stuart) Meek was a descendant of Thomas (1805-1880), but I have no data to support that. However, so far, every Meek that I have researched in the St. Thomas area has turned out to be a descendant of my James Meek, so I am sure we are connected some way.
What is the source of your birth date for Mary Halladay?
