I too am looking for information about this wedding and anything about Amos' time in Waterford, his third son George was my G.G.father, he cut himself off from the family after they returned to Manchester.
The brother in Cork who founded Booth & Fox was in fact John Peter, the eldest bro., George stayed in Derbyshire and was farming before moving into cattle dealing. The Fox part of the Company was Adam Fox who was their brother in law who had married sister Mary.
I have a bit more information and would be happy to exchange it if agreeable
