Hi Mike,
I'm afraid that I'm not good with Scottish records.
Maybe if you post your marriage query on the Scottish board first.
Then when you get the marriage cert that should have his father's name and occupation on it - then come back to us to see can we help.
Our civil registration only began in 1864 so obviously Edward was born well before this so you will be looking for a baptism for him.
As Aghadowey has said this is going to be super hard without you having at least a county in Ireland of origin for him.
