Query: Great - especially if you also have More Irish Families

The best and most up to date reference of Irish Family surnames, their origin, history and in many cases their coat of arms (colour illustrations). MacLysaght corrects many of the errors that appeared in older publications on this subject, including those of Woulfe and O'Hart. Along with More Irish Families by the same author, this is a "must have" if you are interested in Irish surnames.
