RunKitty - I'm going to have to learn to type faster - that's the second time you've beaten me to it!
So, if the 1861 Alfred C LEDELL is the right man, (living in Ontario) and Naomi (of Ontario and Alfred's eldest known child was born c1866 in Ontario then the marriage (assuming there was one) would have been between 1861 and 1866. The censuses have Alfred as Methodist or Baptist - I don't know if that has any relevance.
