An Introduction to Irish Coats of Arms

An Introduction to Irish Coats of Arms

Irish family crests are more than just cool designs on mugs or pub signs. They’re historical reminders of the Irish courage and identity passed down through generations.

Whether you’re proudly Irish or just curious about your roots, exploring Irish heraldry is like stepping into a living history book, filled with warriors, kings, and clans. 


What Makes Irish Heraldry Special?

Irish heraldry is a rich expression of lineage, identity, and national spirit. In Ireland, coats of arms belong to the entire sept, not just one person. That means hundreds of descendants can share one crest. Your distant cousin from 15 generations ago might have the same crest as you! These crests were usually shown on shields and not badges.

You’ll still see them carved on churches, printed on pub signs, and even used in school emblems.


Irish Heraldic System

The Irish heraldic system was formalized in 1552 by the Ulster King of Arms, a crown-appointed officer.

Irish heraldry blends native Gaelic tradition with English and Norman influences. Families that adopted English-style arms often kept Celtic symbols like harps, stags, and the Red Hand (we’ll explore these later), while others stayed fully Gaelic and used older Irish symbols.


Irish Coat of Arms History

Back in medieval times, Irish knights used family crests to show identity during battles. Later on, Irish families used their family crests to display their status and line of work. The oldest known Gaelic seal comes from the O’Kennedy clan way back in 1356 . 

Later, the job of keeping track of all these proud family crests went to the Ulster King of Arms.

And when Ireland claimed its independence, the role passed on to the Chief Herald of Ireland, now based in the National Library, where your family’s legacy might just be sitting between dusty scrolls and national treasures. 

If digging through all that sounds like a lot, our team can help you find your family crest!

Common Symbols in Irish Crests

Here are some of the most popular symbols used in Irish coats of arms:

  • Harp – A symbol of Ireland itself. It stands for national pride, wisdom, and grace. 

  • Shamrock – Linked to Saint Patrick and often used to represent faith and Irish identity.

  • Red Hand of Ulster – A powerful symbol of leadership and legend, tied to the O'Neill family.

  • Animals – Lions (courage), stags (Celtic royalty), boars (bravery), wolves, and salmon (wisdom).

  • Trees – Especially the oak, a symbol of strength and deep family roots.

History of the Irish Harp

The harp didn’t just show up on Irish heraldry and Guinness labels overnight. Its story goes way back to Brian Boru, the last High King of Ireland and, as legend has it, a dab hand at playing the harp himself.

He wasn’t just a ruler but a proud supporter of the arts. One of the oldest harps in existence is named after him, and it’s the blueprint for the classic Irish harp on the official national flag. 

 

Real Irish Families and Their Crests

Here are a few famous Irish families and what their crests say about them.

  • The O’Neills

The O’Neills were powerful leaders in Northern Ireland. Their crest shows a red hand. There’s a wild legend from sometime in the 17th century behind it: a man (O’Neill) cut off his own hand and threw it to the shore just to win a race and claim the shores of Ireland first.

This hand became a symbol of bravery and smart thinking. Today, it still shows up on Ulster’s flag.

  • The O’Sullivans

The O’Sullivans, hailing from Kerry and Cork, weren’t ones to back down. Their crest included a lion for courage, a stag for strength, and a hand clutching a sword with a snake for cleverness and grit. After a crushing battle, Donal O’Sullivan didn’t give up. He led his people on a brutal winter march across Ireland. Only a few survived, but that journey turned them into legends. 

  • The McCarthys

The McCarthys were once powerful rulers in Munster, with deep roots in Ireland’s medieval history. Their crest features a stag, a symbol often linked to peace, leadership, and noble blood. But they’re also remembered for something else: building Blarney Castle. If that sounds familiar, it’s because it’s home to the famous Blarney Stone. According to legend, kissing the stone gives you the gift of eloquence.

These crests are like family flags that show strength, stories, and origins. If you think there’s more to your ancestors’ history, discover some interesting family lore by finding your family crest!

How to Find Your Irish Family Crest

  • Use official records: The Chief Herald of Ireland keeps official records.

  • Check trusted books and online resources: Authors like Fairbairn or the Irish Book of Arms Genealogy Heraldry are good sources. But remember: one of the most common mistakes in finding your family crest is to think all crests apply to everyone with the same surname. Verifying symbols, family history, and even using a family tree as a start can all give you a fuller context to dig into your genealogical research. 

  • Look at symbols: Some crests have fish (like the Farrellys), others have stags (like the O’Sullivans or O’Neills).

  • Know your county: Some crests reflect where your ancestors came from. 

A family crest might seem simple at first, but every symbol and color has its own meaning. It’s not something you can just guess or apply to every surname!

That’s why it’s worth digging a little deeper by trusting us to help find your family crest and decode the symbols and elements that actually fit your family’s history! 


Irish Heraldry in the Modern World

Heraldry today isn’t just in dusty archives. You’ll see it:

  • On pub signs 

  • On graves, plaques, churches, and old buildings

  • In school emblems and sports team logos

  • On souvenir mugs, magnets, home decor, and door knockers


Why Irish Heraldry Still Matters

Even after colonization, famine, and all the big changes Ireland has faced, these family crests serve as reminders to people of their resilience and the strong Irish spirit that shines through every challenge. 

If you love the thrill of digging into your family’s past or are just genuinely curious what your ancestors were up to in their time, finding your family crest  is a great way to partake in a tradition that goes back centuries.
