Hi! I'm back after some researches on my side...
I see difficulty with Elija Mead & Thirza/Theresa [Giddings] being the parents of Samuel:
- Samuel's birth date is 05 March 1853 as provided by the 1901 Canada census as well as by his death notice, who are independent sources, given that the census was not accessible before 1995, at which date Samuel had been dead for 65 years; so the person stating the date on the death notice could not know the date on the census... and, miraculously they are identical!
- the children of that couple that I have found (through Family Search) in the Tilshead registers are: Mary Frances M. (b 25.05.1851), James Giddings M. (b 04.09.1853), Elizabeth Ann M. (b 21.03.1856) and Sarah Jane M. (b 29.04.1859).
So, seems that I will have to stick to my initial guess... to which I will come back in a moment.
Your help is appreciated!
