Number of sisters: 3 ·
Oldest: Sunday ·
Middle: Demitra ·
Youngest: Eliana ·
Heritage: Greek-Canadian

Here is a comparative view of the three sisters based on available sources.

The table above consolidates the most consistent public-facing data.

Who are the Kalogeras sisters?

What are their full names?

According to Briefly (South African news outlet), the sisters’ full names are Sunday Kailea, Demitra Mia, and Eliana Markella. The Wikitubia – Fandom page lists them simply by first names Sunday, Demitra, and Eliana, and describes the channel as “a Greek-Canadian channel by three sisters.”

Are they Canadian or Greek?

Multiple secondary sources describe them as Canadian-Greek. Wikitubia – Fandom uses the phrase “Greek-Canadian,” while Briefly states they were raised in Canada with Greek heritage. User-generated posts on TikTok and Reddit have speculated about mixed-race backgrounds (e.g., father Greek-American, mother Mexican-American), but these are unverified and carry low confidence (TikTok discover page, Reddit).

The implication: Ethnicity is the one area where social media chatter conflicts with the small number of editorial write-ups. Until the sisters address it directly, the safest label is Greek-Canadian.

“The Kalogeras sisters are presented in secondary sources as a trio of Canadian siblings: Sunday Kailea, Demitra Mia, and Eliana Markella.”

— Briefly (South African news outlet)

The pattern is clear: the sisters maintain a consistent public brand, but personal details remain scarce.

How old are each of the Kalogeras sisters?

What is the age gap between the sisters?

Based on Briefly’s profile, the sisters are approximately two years apart. Sunday is the eldest, Demitra the middle, and Eliana the youngest. A TikTok user claiming personal knowledge suggested Sunday is 22, Demitra 19, and Eliana 17 (TikTok), but this is unverified and should be treated as rumor.

Who is the oldest and youngest?

Famous Birthdays (celebrity database) lists Sunday Kalogeras’s birth date as May 26, 2003, making her the oldest at approximately 22. The birthdays of Demitra and Eliana are not publicly recorded. The age range across the three sisters is estimated to be late teens to early twenties, consistent with their content style and school-life references.

Until the sisters themselves provide official ages, any number should be viewed as an approximation.

Are the Kalogeras sisters real sisters?

Are they biological sisters?

Yes. Briefly and Famous Birthdays both describe them as biological sisters sharing the same parents. The Wikitubia – Fandom entry also treats them as siblings, not a friend group. No credible source suggests otherwise.

Do they have the same parents?

The Briefly article states they were “born to the same parents” of Greek descent. A Reddit post speculates the father is from the Aegean islands, but this is not verified. The parents’ names and occupations are not publicly known.

The pattern among the available sources is consistent: the sisters are a biological trio with a Greek family background, but beyond that, details are scarce.

Why are the Kalogeras sisters so famous?

What type of content do they make?

The Kalogeras Sisters channel focuses on challenge videos, pranks, vlogs, and cooking adventures (YouTube channel). Their Wikitubia – Fandom page notes that they produce “fun challenge videos, adventure vlogs, pranks, and social experiments.” The family dynamic—three sisters reacting to each other—is a major draw.

What made them go viral?

Briefly attributes their rapid growth to relatable sibling interactions and shareable challenge formats. Reddit discussions (e.g., this thread) highlight their resemblance and chemistry as factors. The channel surpassed 1.8 million subscribers in about two years, a pace that suggests strong algorithmic pickup (Social Blade estimate).

What this means: the sisters’ success relies on chemistry that cannot be easily replicated, making their channel a standout in the crowded creator space.

What is Eliana Kalogeras real name?

Is Eliana a stage name?

Eliana Kalogeras is listed as one of the sisters in all major sources, including Briefly (Eliana Markella) and Famous Birthdays (Eliana). No alternative or “real” name has been suggested in credible sources. It is likely her given first name.

What are the other sisters’ full names?

Sunday Kailea and Demitra Mia are the full first-and-middle combos provided by Briefly. Famous Birthdays uses Sunday, Demitra, and Eliana without middle names.

Why this matters: The inconsistency across sources underscores the low EEAT of available information. Without a direct statement from the family, even names should be treated as approximate.

What is the ethnicity of the Kalogeras sisters?

Are they of Greek descent?

All secondary sources agree they are Greek-Canadian. Wikitubia – Fandom explicitly labels the channel “Greek-Canadian,” and Briefly says they “were raised in Canada with Greek heritage.” No authoritative source has challenged this.

Where in Canada do they live?

Their city of residence is not publicly disclosed. Famous Birthdays lists “Canada” as a location, and their content often includes suburban backdrops but no specific city.

The trade-off: Fans want more personal details, but the sisters have kept their family life largely offline. This may be intentional to protect privacy, especially for the youngest sibling.

The implication is that until the sisters offer more transparency, reliable biographical data will remain limited.
