By any chance is there any relation to Mark Davidson? I was born and raised with the North Mornington Church, I asked my mom who was also raised in the church if she reconized the names. Unforunately the church was closed October 2012 and is now being used by another church group. My mom also mentioned it would be worth checking with the Presbetry Archive in Toronto as they would hold all the records that the church once had. I hope this helps a little bit if there is anything else I could help you with regarding North Mornignton please let me know.
