  • Origin: Latin; West Frisian
  • Meaning: “light; people.”
  • Gender: Unisex
  • Usage: English, Dutch
  • Pron: LOO-men

Lumen is a name of multiple origins and meanings. It can be from the Latin lūmen (luminis) meaning “light, radiance, illumination.” The term has inspired centuries of philosophical, scientific, and religious imagery. In modern usage, lumen is also a scientific unit measuring luminous flux — the amount of visible light emitted by a source — and in anatomy, it denotes the inner cavity or channel of a tubular organ.

Lumen can also be a West-Frisian unisex name, usually used as a diminutive form of any name beginning with the Liud – element, from the Old Germanic meaning, “people.” There is also the masculine form of Lumman.

In the United States, there are records for male Lumans and Lumens, nicknamed Lummie and Louie as early as the 18th-century. It is unknown if it is based on the Latin term lumen or a family surname, in which case it is most likely from a Dutch patronymic of the aforementioned etymology or other surnames of unknown etymology.

By the early 1900s, it is found as a female name or as a religious unisex name taken by Catholic nuns and monastics, and in the case of many Italian-American females, as an Anglicized diminutive form of Filumena (Philomena).

The name is also used on females in the Philippines as a form of Illuminada.

The name Lumen also appears in literature — notably as the title of Camille Flammarion’s 1887 cosmic novel Lumen, in which a disembodied soul travels through space and time as a being of light. The association deepens the name’s connection to illumination, eternity, and the cosmos.

Lumen Pierce, a character in the fifth season of the television series Dexter (2010), further popularized the name in contemporary culture.

A notable male bearer is American artist, Lumen Martin Winter (1908-1982).

Elegant and radiant, Lumen embodies both scientific precision and spiritual luminosity. Its cross-cultural history — from Latin philosophy to Frisian folk roots to celestial fiction — gives it a timeless, modern-ethereal appeal. Perhaps its the next generation’s Lauren of the 1980s.

  • Origin: English
  • Meaning: “son of Jack.”
  • Usage: English, Dutch (modern use), Brazilian-Portuguese
  • Gender: Male
  • First Est: 18th-century

From the transferred use of the English patronymic surname, it means “son of Jack.” Its use as a given name began in 18th-century England and North America, originally used as an honorific of a family surname. In early 19th-century America, its usage may have accelerated even further due to President Andrew Jackson (1767-1845).

Jackson has been in the U.S. top 1000 boys names since 1880, but did not enter the top 100 until 1998. It peaked at #14 in 2021 and currently ranks in at #35 (2024). Its rankings in other countries are as follows:

  • #23 (Canada, 2023)
  • #62 (New Zealand, 2024)
  • #73 (Australia, 2024)
  • #131 (England & Wales, 2024)
  • #364 (the Netherlands, 2024)

Jackson feels confident, friendly, and American-modern — a name that reads equally well on a child, artist, or CEO. It carries no stuffy baggage and fits neatly with contemporary tastes for short, crisp, strong names ending in -son (Hudson, Grayson, Mason).

Variant spellings include: Jaxen, Jaxon and Jaxxen. Short forms include: Jack and Jax.

Riley

  • Origin: English
  • Gender: Unisex
  • Usage: English, Dutch
  • Meaning: rye meadow.
  • First Est. 1600s (males); 1800s (females)

From the transferred use of the English surname composed of the Anglo-Saxon elements, ryge (rye) and lēah (meadow).

It shares phonetic similarity with the Irish surname Reilly, though the two are etymologically unrelated. Reilly derives from the Gaelic male name Raghailleach, an ancient Irish personal name of uncertain meaning. However, the Riley spelling has long been more common as a given name.

As a male given name, Riley appears sporadically in England as early as the 16th century, likely used in reference to a mother’s maiden surname—a customary naming practice of the period. A few records of female bearers named Riley appear in England beginning in the mid-19th century, though such instances were rare until modern times.

Riley as a male given name became more widespread by the late 1800s. It first entered the U.S. Top 1000 in 1880 and has remained there continuously ever since. The name reached its highest rank in 2002 at #99 for boys, and as of 2024, it stood at #229. His rankings in other countries are as follows:

  • #47 (New Zealand, 2024)
  • #65 (Canada, 2023)
  • #74 (Australia, 2024)
  • #80 (England & Wales, 2024)
  • #85 (Scotland, 2024)
  • #92 (Northern Ireland, 2023)
  • #248 (Netherlands, 2024)

As a female given name, Riley first entered the U.S. Top 1000 in 1990, debuting modestly at #822. It rose steadily throughout the 1990s, entering the Top 100 by 2002 at #72. The name reached its highest point to date in 2017, peaking at #25, and as of 2024, it ranked at #42. Its ranking as a female given-name in other countries are as follows:

  • #50 (New Zealand, 2024)
  • #82 (Australia, 2024)
  • #170 (Netherlands, 2024)
  • #175 (England & Wales, 2024)

The factors driving its sudden popularity are somewhat uncertain. Riley may have appealed to parents as a fresher, lighter alternative to earlier -ley names that had dominated the previous decades, such as Shirley (1920-30s), Beverly (1940s-50s), Kimberly (1960s-70s) and Ashley (1980s-90s). Its crisp, upbeat rhythm and modern unisex sound also contributed to its rise.

Its female version has spun off variant spellings, which may make it even more popular than it seems, such as Reiley, Reilly, Reily, Rhilee, Rhiley, Rhylee, Rhylei, Rhyleigh, Rhyley, Rhyli, Rhylie, Rielee, Rilee, Rileigh, Rilie, Ryelee, Rylea, Rylee, Rylei, Ryleigh, Ryley, Ryli, Rylie, Ryliee, and Ryliegh.

Its usage as a unisex same has spread recently to the Netherlands, where it ranks in the charts, though not as high as in the anglosphere.

Reilly will have its own entry. Look for further posts in the future.
