Which Church did they marry in?

It turns out that my Great Great Uncle Robert Gow & his wife Mary Ryan married in the Catholic Church…

I suppose there was an increased risk for Mary being ostracized from her family if she did not marry in the Catholic Church. A risk that was greater than if Robert didn’t marry in a Presbyterian church I suppose. Hmm. Now I’d like to find out when Mary came to Australia & if her parents came with her too as I have’t been able to discover that as of yet…
