Origin
Meaning and origin of Mcdarment
The surname McDarment has its origins in Scotland, dating back to the 16th century. It is believed to be derived from the Gaelic words "mac" meaning "son of" and "dara" which translates to "oak tree." This suggests that the name may have been initially given to someone who lived near or had a connection with an oak tree.
One of the earliest recorded instances of the name McDarment can be found in the parish records of Ayrshire, Scotland, from the late 1500s. The name appeared with various spellings such as McDairmid, McDairmant, and McDarmant, reflecting the phonetic nature of the name's evolution.
In the 17th century, the McDarment family seemed to have established a presence in the Scottish Lowlands, particularly in the regions of Lanarkshire and Renfrewshire. The name is also associated with the village of Darvel, located in East Ayrshire, where some McDarments resided during this period.
One notable McDarment from the 18th century was John McDarment (1725-1810), a Presbyterian minister who served as the minister of Campbeltown, Argyll. He was known for his influential sermons and his role in the Secession Church movement.
In the 19th century, the McDarment name gained prominence with the birth of Alexander McDarment (1825-1902), a Scottish-born Australian politician and businessman. He was a member of the Legislative Council of Western Australia and played a significant role in the development of the state's mining industry.
Another notable figure was William McDarment (1860-1932), a Scottish-born Australian architect who designed several landmark buildings in Melbourne, including the Melbourne Town Hall and the Gothic Bank Building.
As the McDarment family spread across the globe, the name appeared in various records and historical accounts. For instance, James McDarment (1890-1964), an American author and journalist, wrote several books on historical topics, including one on the famous American outlaw Jesse James.
The name McDarment has also been linked to several place names in Scotland, such as McDarment's Knowe, a hill in Lanarkshire, and McDarment's Loch, a small body of water located in the same region.
Overall, the surname McDarment has a rich history that can be traced back to its Scottish roots, with various branches of the family leaving their mark across different parts of the world throughout the centuries.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.

Keep in mind that these are self-reported numbers.
