Hello, we're still following this avidly, after "butting in" a while ago in respect of our interest in Robert Allen of Glenleary and the possible (father-daughter?) link with our Margaret Ann[e] Allen (sometimes 'Peggy', never 'Maggie'......). And our interest is because she became Margaret/Peggy McMichael and now rests [alone] in the smallest graveyard in front of Macosquin Pres. Ch.
Anyway, I know the thread is on a different tack just now - equally intriguing - but reading the discussion about (Isa-)Bella Allen and her marriage cert, I checked pictures my husband took in Macosquin Presbyterian last May, and (I am sure LyndeL and aghadowey will have seen this - attempting photo upload) - but it struck me the name of the female witness on the church register was a "Mary McMichael." Now someone called Mary McMichael was - definitely - the firstborn of Peggy (ne้ Allen, daughter of Robert) with Daniel McMichael. And - relying on Peggy Allen's marriage cert - Mary is a granddaughter of someone called "Robert Allen, a farmer, of Glenleary". (Granted, as Lindel has said, the possibility of two Robert Allens in Glenleary in the 1850s onwards isn't impossible though we haven't found two distinct evidence groups either...)
Mary herself was born 1870 and baptised in Macosquin Presbyterian Church where the family then resided til the 1890s. So, she's born 3 yrs before Bella, then married 2 years after her and is (conjectural) at one with the witness at Bella's marriage. The dates are not bad.
If the tempting links and our suppositions (that Peggy may just possibly be a sister of Sarah albeit 'missing' from other records discussed above) are right, then this could theoretically be Mary witnessing her cousin's wedding. Which may be further circumstantial evidence for a link, ie Robert Allen's & Betty Henry's family, with Peggy McMichael's descendants. This is added to the fact, mentioned above, that her second sister [Bessie McMichael] bore the middle name 'Henry'.
Except for that "Father - John Smith" reference which does rather upset things. So my husband will be very interested how the "John Smith" dimension is resolved.... As I say - intriguing.
