Mary McMahon, Shanagolden, Limerick
I am looking for information on my great great grandmother, Mary McMahon of Shanagolden Limerick. She was borm 1808.
She was married and then widowed, unsure of date then married my great great grandfather James Callaghan at Shanagolden (He was from Cork) they had children, I think some from the previous marriage. They emigrated to Australia on the Duchess of Northumberland in 1836, then to New Zealand in 1838.
Family story that Mary was cousin to Field Marshall McMahon, one of Napoleon's generals.
They left eldest son in Ireland "in the care of his grandfather". This son made enquiries about the family later through Baron Mounteagle with a view to joining them in New Zealand.
Any information or connections would be welcome
