Three young daughters, first-party records and no invented child biographies

Mark Zuckerberg’s 3 Daughters: Max, August and Aurelia

The strongest answer is disciplined and deep in evidence: use the parents’ own letter for Max, CZI’s family record for August and Mark’s archived birth announcement for Aurelia, while excluding theories about names or culture that the parents did not establish.

An announcement date is not automatically a civil birth date. This guide labels that distinction, calculates ages only to the defensible level and does not infer personality, schooling, language, religion, interests or future work for any child.

Mark Zuckerberg’s daughters at a glance

Max is the eldest, August the middle daughter and Aurelia the youngest. All three use both Chan and Zuckerberg in the public names their parents supplied.

For another privacy-first technology family, compare Jeff Bezos’s four-child evidence guide. Bill and Melinda French Gates’s three children shows how public-parent roles can be separated from adult children’s identities.

What the first-party record actually establishes

Mark and Priscilla married in 2012 and are the parents of all three daughters. The Chan Zuckerberg Initiative began alongside Max’s arrival in 2015, and its official annual letters refer directly to Max and August as their children.

Aurelia’s arrival was announced through Mark’s verified social account in March 2023. A university archive preserves the source URL and publication date, giving the announcement a stable provenance even when a social platform is difficult to access.

Maxima “Max” Chan Zuckerberg

Max was born in 2015. Mark and Priscilla published their “Letter to Max” on 1 December, writing to their new daughter and setting out hopes for the world in which she would grow up. The letter also announced the mission that became CZI.

CZI’s 2019 annual letter says Max had turned four “a few days” earlier, supporting late November 2015 rather than proving that 1 December was her civil birthday. “Born by 1 December” is therefore more precise than copying the letter’s publication date into a birthday field.

August Chan Zuckerberg

August was born in late August 2017. CZI’s official photo record identifies Mark and Priscilla at home with Max and August on 29 August 2017. Their annual letters later call August their second child and Max’s sister.

The parents’ public letter to August focused on childhood and play. It does not establish her current hobbies or personality nine years later, so this guide does not recycle the letter’s hopes as biographical traits.

Aurelia Chan Zuckerberg

Aurelia’s arrival was announced on 24 March 2023. Mark’s post named her “Aurelia Chan Zuckerberg” and called her a blessing. The post establishes the child, her public name and the announcement date.

It does not explicitly publish a time of birth or civil certificate date. Reputable same-day reporting confirms she is the third daughter, but the responsible table says “arrival announced” rather than silently changing publication time into birth time.

Why do the dates use different precision?

Precision is not the same as accuracy. A full date looks authoritative, but it is weaker if the source merely announced a birth on that day. Showing the evidence level makes the article easier to maintain and harder to misquote.

How does CZI relate to the family?

CZI’s origin story is relevant because the parents tied it directly to Max’s birth and their hopes for children’s future. That does not make the daughters responsible for the organisation or turn philanthropic goals into their personal views.

What is deliberately not included?

No school, address, routine, health detail, personality label or “future CEO” prediction appears here. The parents have occasionally shared family moments, but three children’s names do not create consent for a composite profile assembled across years.

Name-origin theories are also excluded unless the parents state them. Similarity to Roman names or a parent’s interests may be an internet observation; it is not evidence of why a child was named.
