I’m researching my family called Guinan. They were based in North Cork, Ireland (Doneraile) but seemed to emigrate en-masse to London (St Pancras, Middlesex etc.) in the 1830s. I have identified a John Guinan marrying Bridget Callaghan around that time but I am unsure whether it was in Ireland or England. Their ancestors are still in London but the branch that particularly interests me returned to Cork City around the 1900s. Any help.guidance would be greatly appreciated.
