Stephen Miller Children: Meet Mackenzie, Jackson, Hudson and Hawthorne, His Four Kids With Katie Miller
Stephen Miller’s selection as the next White House chief of staff on November 6, 2026, comes during a year in which his family also grew. The political adviser and his wife, Katie Miller, welcomed their fourth child, Hawthorne Hayes, in June. They now have one daughter and three sons: Mackenzie Jay, Jackson Grant, Hudson Monroe and Hawthorne Hayes Miller.
President Donald Trump announced that Miller would succeed Susie Wiles beginning November 9. The appointment has renewed attention to a household whose parents both built careers in Republican politics, although the children themselves are young and have no public professional roles.
The youngest child’s arrival is an important update to older family profiles. Articles written before June 2026 may correctly describe Stephen and Katie as parents of three at that time, but that total is no longer current. Their fourth baby was born on June 3, with Katie announcing the news on June 10.
The family’s publicly shared milestones establish the children’s names and the order of their arrivals. Beyond those announcements, details about their individual personalities and daily routines are limited. Photographs and brief comments from their parents offer a partial view of family life, rather than a complete account of how the children are being raised.
Who are Stephen Miller’s four children and how old are they?
Mackenzie Jay Miller is the couple’s eldest child and only daughter. She was born on November 19, 2020, several months after her parents’ wedding. As of November 7, 2026, she is five and approaching her sixth birthday. Her arrival made Stephen and Katie first-time parents.
Their first son, Jackson Grant Miller, followed on February 25, 2022. He is four as of the date of this article. Jackson became an older brother the following year, when the couple welcomed another boy, Hudson Monroe Miller, on September 7, 2023.
Hudson is now three. The three older children were joined by Hawthorne Hayes Miller on June 3, 2026. Hawthorne is five months old in early November, making the children a closely spaced group spanning infancy and early childhood.
The names Jackson Grant and Hudson Monroe have sometimes been shortened to Jackson and Hudson in news reports. Similarly, Mackenzie and Hawthorne may appear without their middle names. Those variations do not indicate additional children or different family members.
What did Katie Miller share about the birth of Hawthorne Hayes?
Stephen and Katie announced the fourth pregnancy around New Year’s Eve, ahead of Hawthorne’s June arrival. Katie later confirmed his birth with a collection of family photographs. The announcement included the newborn alongside images showing the older children and their parents together.
Her message expressed enthusiasm for parenthood and described a busy, affectionate household. It was a personal birth announcement rather than a formal White House statement. Coverage of it identified Hawthorne by name and reported that he was born on June 3.
The announcement came after weeks of public interest in Katie’s pregnancy. She had attended the White House Correspondents’ Dinner in April while heavily pregnant, and photographs of the couple leaving during the security incident at that event had drawn extensive online discussion.
That earlier episode and the later birth announcement are separate events. Hawthorne was not born at the dinner, and images from April should not be described as photographs of his arrival. Accurate captions and dates help distinguish the pregnancy period from the family’s June update.
Who is their mother and what have the parents said about family life?
The children’s mother is Katie Miller, formerly Katie Waldman. She and Stephen married on February 16, 2020, at the Trump International Hotel in Washington, D.C. They met through their work and mutual friends during Trump’s first administration.
Katie previously worked in communications for the Department of Homeland Security and Vice President Mike Pence. She later worked on the government efficiency initiative associated with Elon Musk before developing her own media platform. The Katie Miller Podcast launched in August 2025.
Motherhood has featured in how she describes that project. When launching it, she spoke about wanting a space for conservative women managing children, marriage, careers and personal interests. At that point, the Millers had three children; Hawthorne’s arrival expanded the family the following year.
Katie has also publicly discussed security concerns affecting the household. Reporting in late 2025 described the family moving into military housing after threats. Those accounts concern the parents’ explanation of their circumstances and do not justify publishing the children’s precise location or private routines.
For readers seeking the current family count, the answer is four. Mackenzie, Jackson, Hudson and Hawthorne are Stephen and Katie Miller’s children, and June 2026 marks the most recent verified addition to the family.
