Thank you for your prompt reply, any reply is better than none.
Unfortunatly all of their children where born in Liverpool, so I don't have anything to go on.
They show up on the UK census which states that they where both born in Clare, but I have no idea what Parish, although I have been told that there are a lot of Mangan families in Kilrush. I presume that they both died in Liverpool too. It's so frustrating as I would love to find out more about this family. The place where Simon worked as a shoemaker was only a stones throw away from where I was born too, and I would love to know more about them.
Many thanks for your advice.
