Very keen to be in touch with anyone descend from Nell O'Brien and John Twohig. Their children included Michael, Alpho, Kathleen, Frank, and Joe. As far as I know, they all used both their parents names either going by "O'Brien Twohig" or "O'Brien-Twohig". Based on the information available to me, I believe their descendants would live in the UK, Australia, and possibly South Africa.
