I`m not sure if there is connection between us buy I am distantly related to Margaret Joyce who was the wife of Michael Broderick. Margaret was born in 1840 and I know she had children called Margaret, Michael, Jane (McGrath) Patrick, Delia Mary and John (maybe others). I have recently been researching the life of one of her children Sir John Joyce Broderick who carved out a successful career in the diplomatic service. I would be willing to share any information with you if you wish. I would be pleased to hear from you.
