Description:
People ask me all the time where in Ireland their surname may be found. A lot of these people, their ancestor/s left Ireland pre the ‘main’ famine time so they never think to look in records that we have which are for a time later than that famine period, and they should, they should particularly look at the distribution in the Griffiths Primary Valuation as per the examples I give below.
