Today, surnames such as MacDonald, MacKenzie and MacGregor are recognised around the world. They provide a fascinating link to Scotland’s history, language and clan traditions.

Quick Summary

• Mac means “son of” in Gaelic.
• Many Scottish surnames developed from family relationships.
• Mc is simply an abbreviation of Mac.
• Both forms are historically correct.
• Many Mac surnames have strong connections to Scottish clans.

What Does Mac Mean?

The prefix Mac comes from the Gaelic word for “son”.

For example, MacDonald originally meant “son of Donald”, while MacGregor meant “son of Gregor”. These names helped identify family relationships in early Scottish communities.

As generations passed, the names became hereditary surnames rather than descriptions of an individual’s father.

Many Scottish surnames still retain these ancient Gaelic roots today.

Why Do Some Names Use Mc Instead of Mac?

One of the most common questions about Scottish surnames concerns the difference between Mac and Mc.

The simple answer is that Mc is an abbreviation of Mac.

Historically, scribes often shortened Mac when writing records, saving both time and space. Over the centuries, these shortened versions became established surnames in their own right.

As a result, you may find both forms in use today.

Examples include:

• MacDonald and McDonald
• MacArthur and McArthur
• MacKenzie and McKenzie

Neither version is more correct than the other. The spelling often depends on family tradition, historical records and regional usage.

The Connection Between Mac Surnames and Scottish Clans

Many Mac surnames are closely associated with Scottish clans.

A clan was much more than an extended family. It was a community connected by loyalty, shared ancestry and common identity. Clans often controlled territories, maintained strong traditions and played important roles in Scottish history.

Names such as MacDonald, MacLeod, MacDuff and MacGregor remain strongly linked to famous clans today.

However, not every person sharing a clan surname is necessarily descended from the same ancestor. Clan structures were often complex and included many associated families.

In Scotland, many surnames are connected to larger clans as what are called septs. A sept is a family or group of families who may not share the same surname as the clan chief but historically owed allegiance to the clan.

Septs were often smaller branches of a clan, families living in the same area, or households brought under the protection of a chief. This system allowed clans to grow, form alliances, and strengthen ties across regions.

For example, the MacLaren clan historically included septs such as McFarlane and McLachlan. These families were connected to the clan through loyalty, shared ancestry, or protection agreements, even if their surnames differed.

Why Septs Matter in Heraldry

Septs do not automatically have the legal right to the clan chief’s coat of arms. The Lord Lyon King of Arms grants arms to individuals, not surnames or clans. However, members of septs often use a crest badge or elements from the chief’s heraldic symbols to show their connection.

These badges may include:

• Crests from the chief’s arms
• Plants or heraldic symbols indicating allegiance or shared heritage
• Strap-and-buckle designs encircling the crest to show it belongs to the clan chief

This distinction is important: sept members can display a badge symbolically, but it does not give legal entitlement to the arms themselves.

Clan and Surname History Prints

Our Scottish Clan History Print is ideal for exploring the history of a clan, including its symbols, crest, and associated families. If your surname is actually the clan name, this print gives a full picture of your clan’s heritage and heraldic symbolism.

However, if your surname is a sept of a larger clan, the Clan History Print will show the history of the main clan rather than your surname specifically. In that case, the Coat of Arms and Surname History Print is the better choice. It focuses on the earliest recorded arms linked to your own surname, giving detailed history, symbolism, and context specific to your name.

Both prints are also available as digital downloads, so you can view, print, and share your surname heritage instantly—perfect for overseas customers or families wanting multiple copies.

Customer Experiences

Our prints are valued for both their historical detail and visual appeal. Jane said of the Coat of Arms and Surname History Print, “Such prompt service.” Malcolm added, “The quality and the history about the name is fantastic. Would recommend your company to anyone who is looking to find the history of their name.”

Sharing and Learning About Septs

Many customers enjoy sharing their surname and clan prints online with relatives. Our Facebook page is a great place to post images, share stories, or see how others display their clan and surname heritage.
