Popular baby names in Kent County (Michigan), 2025

Flag of Michigan
Flag of Michigan

More than 10,500 babies were born in Kent County, Michigan, during the first eleven months (or so) of 2025.*

What were the most popular names among these babies? Sophia and Henry, according to data from Kent County’s Office of Vital Records.

Here are the county’s probable top 10 girl names and top 10 boy names of 2025:

Girl names

  1. Sophia
  2. Charlotte
  3. Emma
  4. Amelia
  5. Harper
  6. Josephine
  7. Nora
  8. Eleanor
  9. Lucy
  10. Violet

Boy names

  1. Henry
  2. James
  3. Theodore
  4. Oliver
  5. Hudson
  6. Bennett
  7. Jack
  8. Noah
  9. Wesley
  10. Levi

One year earlier, the top names state-wide were Charlotte and Noah, according to the SSA. (Sophia ranked 6th and Henry ranked 4th.)

Finally, did you know that the current Kent County clerk is named Lisa Posthumus Lyons? She wasn’t born after the death of her father, like the babies named Posthumus centuries ago; Posthumus is simply her maiden name. (Her father, Michigan politician Dick Posthumus, is still alive.)

*The rankings were posted to Kent County’s social media accounts on December 3rd, so I’m assuming they cover the year from January to November.

In the girls’ top 10, Clara and Sofia replaced Lea and Juliette.

In the boys’ top 10, Emile and Theo replaced Jacob and Nathan.

And what about the names at the other end of the spectrum?

Among those given to fewer than five babies, I spotted the place names Kenai and Sitka, the plant name Melilot (sweet clover), the French word Tantine (meaning “auntie”), and the Inuktitut versions of various Christian names:

  • Joanassie (based on John, Jonah, or Jonas)
  • Jusipi/Juusipi (based on Joseph)
  • Paulusie (based on Paul)
  • Silasie (based on Silas)
  • Tuumasi (based on Thomas)
  • Elisapee/Elisapi/Elisapie (based on Elizabeth)

I also noticed names from various indigenous languages, such as…

  • Aqiaruk, which means “stomach” in Inuktut.
  • Arnaq Talittuq, made up of the Inuktitut words arnaq, meaning “woman,” and talittuq, meaning “disappears, hides.”
  • Maikaniss, which means “wolf cub” in Innu. (The word maikan means “wolf.”)
  • Mispun, which means “it is snowing” in East Cree.
  • Missinak, which means “turtle” in Innu.
  • Nipinok, based on the Cree word nipinohk, meaning “last summer.” (The word nipin means “summer.”)
  • Piponik, based on the Cree word pipon, meaning both “winter” and “year.”
  • Putulik
  • Qumaluk
  • Tillikasak
  • Timangiak
  • Uashtessiu, part of the Innu term uashtessiu-pishimu, meaning “the month when the leaves become yellow” (i.e., October).
  • Uiviru
  • Ulluriaq, which means “star” in Inuktitut.
  • Weetalutuk

(I can’t give you the usual sampling of Quebec’s single-use names because, as of 2024, the province has decided to stop specifying which names were given to just one baby. The single-use names — along with the names that were given to two, three, and four babies — are now labeled “<5” in the data.)

Finally, here’s a link to Quebec’s 2023 rankings, if you’d like to compare last year to the year before.

At the other end of the spectrum I spotted Bryher (given to 5 baby girls), no doubt inspired by Bryher Island, located off the coast of Cornwall.

And, speaking of rare names, here’s a selection of those that were given to just three babies each in England and Wales (combined) in last year:

Rare girl namesRare boy names
Ascia, Barley, Clementina, Drashti, Euphemia, Fodhla, Gwenlli, Hyacinth, Isidora, Jindh, Kanak, Letizia, Migle, Ngoc, Olayinka, Pearly, Quinnie, Rennala, Sorella, Tirion, Unathi, Valora, Wallis, Xanthi, Yuet, ZhilaAelfred, Bramwell, Canelo, Doulton, Erling, Ferdia, Gursimran, Horace, Iorwerth, Jolyon, Kenshin, Llywelyn, Mawgan, Nikunj, Ozair, Penuel, Quintus, Rudolph, Shabsi, Teifion, Ugnius, Vishvam, Western, Xyleek, Ynyr, Zaroon

Some facts/thoughts about a few of the above…

  • Canelo is the Spanish word for “cinnamon.” (It’s also used as a nickname for a redheaded person.)
  • Erling is the first name of Norwegian soccer player Erling Haaland (who currently plays for Manchester City).
  • Gwenlli is a short form of the Welsh name Gwenllian.
  • Migle is based on the Lithuanian word migla, meaning “mist.”
  • Teifion may be based on the name of the River Teifi in Wales.
  • Xyleek, which debuted impressively in the U.S. data last year, may have been inspired by a TikTok video.
  • Ynyr is the Welsh form of the Latin name Honorius.

Finally, here are the 2024 rankings for Scotland and Northern Ireland — the other two countries in the United Kingdom — and the 2023 rankings for England and Wales, if you’d like to compare last year to the year before.
