Origin
Meaning and history of Jeffifer
The name Jeffifer is a unique and relatively modern creation, with no clear historical origins or linguistic roots. It is believed to be a variant or misspelling of the more common name Jennifer, which itself is a modern English rendition of the ancient Welsh name Gwenhwyfar.
Gwenhwyfar is derived from the Welsh words "gwen," meaning fair or white, and "hwyfar," meaning smooth or soft. Thus, the name Gwenhwyfar can be interpreted as "the fair and smooth one." This name was borne by the legendary Queen Guinevere, the wife of King Arthur in Arthurian romances and folklore.
The earliest known record of the name Jeffifer dates back to the late 20th century, with no significant historical figures bearing this particular spelling. However, some notable individuals named Jennifer include Jennifer Aniston, an American actress born in 1969, Jennifer Lopez, an American singer and actress born in 1969, Jennifer Lawrence, an American actress born in 1990, Jennifer Garner, an American actress born in 1972, and Jennifer Connelly, an American actress born in 1970.
While the name Jeffifer may be a modern invention or typographical error, its similarity to Jennifer and the underlying Welsh roots of Gwenhwyfar lend it a sense of connection to the ancient traditions and legends associated with the name. Despite its lack of a well-documented history, Jeffifer stands as a unique and intriguing variation that adds to the rich tapestry of given names.

FAQ
Jeffifer: questions and answers
How many people in the U.S. are named Jeffifer?
Name Census puts the figure at roughly 157 living Americans. We arrive at this by taking every SSA birth registration for Jeffifer 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 2,183,149 US residents.
Is Jeffifer a common name?
We classify Jeffifer as "Very Rare". It ranks above 70.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 170 babies have been registered with this name.
When was Jeffifer most popular?
The single biggest year for Jeffifer was 1978, when 12 babies received the name. The fact that the average living Jeffifer is about 45 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 Jeffifer in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jeffifer a female name?
Yes, 100.0% of people registered as Jeffifer 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 Jeffifer still being used today?
Yes. The SSA still recorded Jeffifer 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 Jeffifer 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.
