Another example in my family in Ontario, Canada, was when the itinerant preacher was
passing through and baptized my FERGUSON great-grandfather and all his siblings in January
1854 after the birth of the youngest child. I believe this was quite common then.
Fortunately, the Anglican preacher (previously an RC priest) kept excellent records which
are in the Ontario archives. I have no proof of the parents marriage circa 1818 but the
preacher did name the couple as husband and wife.
