Origin
Meaning and history of Sinnie
The name Sinnie traces its origins to the Old English language, derived from the word "sin," meaning "sin" or "transgression." It emerged during the Anglo-Saxon period, spanning the 5th to the 11th centuries in what is now England. The name may have initially been used as a descriptive term for someone perceived as sinful or prone to wrongdoing.
In the early medieval period, Sinnie appeared in various Anglo-Saxon records and chronicles, often associated with individuals who were involved in religious or moral conflicts. One notable example is Sinnie the Penitent, a 7th-century monk from Northumbria, who gained recognition for his acts of repentance and spiritual devotion.
During the Middle Ages, the name Sinnie was occasionally found in ecclesiastical records, particularly in regions with strong Anglo-Saxon influences. It was sometimes bestowed upon individuals who had committed grave sins or sought redemption through religious means.
One of the earliest documented individuals with the name Sinnie was a 9th-century Anglo-Saxon noblewoman known as Sinnie of Wessex (c. 810-870). Historical accounts suggest she played a significant role in the political affairs of the Kingdom of Wessex during the reign of King Ethelwulf.
In the 12th century, a notable figure named Sinnie the Scribe (c. 1120-1190) gained recognition for his contributions to the preservation of ancient manuscripts and texts. He worked as a copyist and illuminator in the scriptoria of various monasteries across England.
Another individual of note was Sinnie the Minstrel (c. 1250-1320), a wandering musician and storyteller who entertained noble households and commoners alike with his ballads and tales during the late Medieval period.
In the 16th century, Sinnie Hawkins (c. 1540-1610) was a renowned English herbalist and apothecary, renowned for her knowledge of medicinal plants and her skill in concocting remedies for various ailments.
One of the later historical figures bearing the name Sinnie was Sinnie Wycliffe (1670-1745), a English philosopher and theologian who challenged certain religious dogmas and advocated for a more rational approach to faith and scripture interpretation.
While the name Sinnie has faded from common usage in modern times, its historical significance lies in its association with individuals who often grappled with moral dilemmas, sought redemption, or contributed to the preservation of knowledge and cultural traditions.

FAQ
Sinnie: questions and answers
How many people in the U.S. are named Sinnie?
Name Census puts the figure at roughly 3 living Americans. We arrive at this by taking every SSA birth registration for Sinnie 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 114,251,446 US residents.
Is Sinnie a common name?
We classify Sinnie as "Very Rare". It ranks above 4.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 33 babies have been registered with this name.
When was Sinnie most popular?
The single biggest year for Sinnie was 1916, when 7 babies received the name. The fact that the average living Sinnie is about 78 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 Sinnie in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Sinnie a female name?
Yes, 100.0% of people registered as Sinnie 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 Sinnie still being used today?
Yes. The SSA still recorded Sinnie 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 Sinnie 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.
