Census
Sennie in the 2020 Census
The 2020 Census recorded 120 people with the first name Sennie, which placed it at #50,338 in the published first-name tables. This is a snapshot of people who already had the name at the time of the Census.
The SSA sections elsewhere on this page answer a different question: how often parents gave the name to babies over time. The "people living today" figure on this page is different again: it is a current estimate built from SSA birth records and age-based survival rates, so the two numbers are not expected to match exactly.

Demographics
Ancestry and ethnicity for Sennie
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Sennie is Black at 60.0%. The next largest groups are White (20.0%) and Hispanic (7.5%). These figures describe the people who had the name in 2020, not any inherent property of the name itself.
The bar chart below shows how people with the first name Sennie described their own race and ethnicity on the 2020 Census form. 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 name, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown so the breakdown is easy to read across every published category. Because the 2020 Census first-name file also includes raw headcounts for each group, Name Census can show those alongside the percentages in the legend and hover tooltip.
Keep in mind that these are self-reported numbers. A first name does not determine a person's race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the name Sennie at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Sennie
The given name Sennie has its origins in the Scottish Gaelic language, stemming from the word "sìonaidh," which means "well-beloved" or "beloved one." The name's earliest recorded usage dates back to the 16th century in the Scottish Highlands.
Sennie is a diminutive form of the Gaelic name Seònaid, which is the Scottish equivalent of the English name Janet. It's believed that Seònaid itself is derived from the ancient French name Jeanette, a feminine form of the male name Jean or John.
One of the earliest recorded instances of the name Sennie can be found in the Scottish Clan Campbell's historical records from the late 1500s, where a woman named Sennie Campbell is mentioned. She was the daughter of a prominent clan member and is said to have played a crucial role in mediating disputes between rival clans during that tumultuous period.
In the 17th century, a notable figure named Sennie MacLeod lived in the Isle of Skye. She was renowned for her skill in traditional Gaelic weaving and is credited with preserving many ancient weaving techniques that might have otherwise been lost.
During the 18th century, a Sennie MacDonald from the Hebrides Islands gained recognition for her remarkable skill as a storyteller. Her tales, passed down through generations, became an essential part of the region's oral tradition and helped keep the Gaelic language and culture alive.
In the early 19th century, a woman named Sennie MacKenzie was celebrated for her bravery and resilience during the Highland Clearances. She refused to leave her ancestral lands and stood up against the forced evictions, becoming a symbol of resistance for her community.
Another notable figure was Sennie Grant, a 19th-century Scottish poet and writer from Aberdeenshire. She published several collections of poems and short stories that captured the essence of rural life in the Scottish Highlands, preserving the region's rich cultural heritage.
While the name Sennie may not be as commonly used today, its historical significance and deep roots in Scottish Gaelic culture make it a cherished part of the country's naming traditions.

FAQ
Sennie: questions and answers
How many people in the U.S. are named Sennie?
Name Census puts the figure at roughly 28 living Americans. We arrive at this by taking every SSA birth registration for Sennie 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 12,241,226 US residents.
Is Sennie a common name?
We classify Sennie as "Very Rare". It ranks above 45.4% of all first names in the SSA dataset by living bearers. Across the full history of the data, 192 babies have been registered with this name.
When was Sennie most popular?
The single biggest year for Sennie was 1919, when 13 babies received the name. The fact that the average living Sennie is about 77 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Sennie in the 2020 Census?
The published 2020 Census first-name tables recorded 120 people with the name Sennie, or 0.04 per 100,000 residents. That placed it at #50,338 in the national Census ranking for first names.
Why is the Census count different from the living estimate?
Because they measure different things. The Census figure is a count of people who had the name Sennie in 2020. The living estimate aims to answer a current question instead: how many people with the name are alive today, based on SSA birth records and age-based survival rates. Since one number is a 2020 snapshot and the other is a present-day estimate, they are not expected to be identical.
What does the Census say about the gender split for Sennie?
In the 2020 Census sex table, Sennie leans strongly female. 112 people counted with this name were female (91.8%), compared with 10 male bearers (8.2%). The Census view is a snapshot of people living with the name in 2020, while the SSA section above tracks births across time.
What does the Census say about the background of people named Sennie?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Sennie is Black at 60.0%. The next largest groups are White (20.0%) and Hispanic (7.5%). These figures describe the people who had the name in 2020, not any inherent property of the name itself. The percentages in the chart above come from self-reported race and Hispanic-origin responses in the 2020 Census.
Which group reports the name Sennie most often in the Census?
Black is the largest reported group for people named Sennie in the 2020 Census, accounting for 60.0% (72 people in the published table).
Why can the Census sex total and race total differ slightly?
The Census Bureau published separate 2020 tables for sex and for race/Hispanic origin, and the released figures can differ slightly because of privacy protection in the public files. That is why this page treats the gender section and the race/origin section as two related snapshots instead of forcing them into one identical total.
Does every first name have Census demographic data?
No. The public Census first-name release only includes names that met the Bureau's publication rules, so many rarer names in the SSA files have no Census demographic snapshot. When that happens, the SSA trend, gender history, and state sections still appear, but the 2020 Census demographic sections are omitted.
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 Sennie in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Sennie a female name?
Yes, 100.0% of people registered as Sennie 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 Sennie still being used today?
Yes. The SSA still recorded Sennie 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 Sennie 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.
