If you decide to not hire a Genealogist, you may find yourself trying to determine what an unfamiliar Irish last name is from an old document, such as a Death Certificate or a Marriage Record. This list will help identify some of those names.

1. Murphy – the sea battlers
2. Kelly – the bright-headed ones
3. O’Sullivan – the hawkeyed ones
4. Walsh – the Welshmen
5. O’Brien – the noblemen
6. Byrne – the ravens
7. Ryan – the little kings
8. O’Connor – patrons of warriors

Note – The names Smith and Murray both made the top 10, but Smith is British and Murray of Scottish origin, so they are excluded from the list.
