Origin
Meaning and history of Siddie
The name Siddie originates from the Scottish language and culture, with its earliest recorded use dating back to the late 16th century. It is believed to be a diminutive form of the name Sidney, which itself is derived from the Old English words "sid" and "eg", meaning "wide" and "island" respectively.
In Scotland, the name Siddie was commonly found in the Lowlands region, particularly in the counties of Ayrshire, Renfrewshire, and Lanarkshire. It was often used as a nickname or pet name for those with the given name Sidney or similar variations.
One of the earliest recorded mentions of the name Siddie can be found in the Perth Kirk Session Records from 1598, where a woman named Siddie Mackay is listed. This provides evidence of the name's use in Scotland during the late Renaissance period.
Throughout history, there have been several notable individuals who bore the name Siddie. One such person was Siddie Mackenzie (c. 1660 - 1735), a Scottish noblewoman and Lady of the Bedchamber to Queen Anne of Great Britain. She was renowned for her wit and intelligence, and played a significant role in the political and cultural life of the early 18th century.
Another notable Siddie was Siddie Campbell (1785 - 1861), a Scottish poet and songwriter from the Isle of Islay. She is best known for her collection of Gaelic songs and poems, which helped preserve the rich oral tradition of her native island.
In the 19th century, Siddie Macleod (1814 - 1892) was a prominent figure in the Scottish Highland Clearances. She was a crofter who vehemently opposed the forced evictions of tenants from their ancestral lands, and became a vocal advocate for the rights of crofters and smallholders.

FAQ
Siddie: questions and answers
How many people in the U.S. are named Siddie?
Name Census puts the figure at roughly 1 living Americans. We arrive at this by taking every SSA birth registration for Siddie going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 342,754,338 US residents.
Is Siddie a common name?
We classify Siddie as "Very Rare". It ranks above 3.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 59 babies have been registered with this name.
When was Siddie most popular?
The single biggest year for Siddie was 1888, when 8 babies received the name. The fact that the average living Siddie is about 79 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Siddie in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Siddie a female name?
Yes, 100.0% of people registered as Siddie in the SSA data are female. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Siddie still being used today?
Yes. The SSA still recorded Siddie in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Siddie can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
