David Tennant’s Biography: Family, Health, and Career Facts

David Tennant has been a fixture on British screens for two decades, from his electrifying turn as the Tenth Doctor to his sly Crowley in Good Omens, but fans are also curious about his personal life: his five children, his wife Georgia Moffett, and the rumours about his health. Here’s a fact-checked look at what’s confirmed and what remains unclear about the man behind the sonic screwdriver.

Full name: David John Tennant (né McDonald) · Born: 18 April 1971, Bathgate, Scotland · Known for: Doctor Who, Broadchurch, Good Omens · Spouse: Georgia Moffett (m. 2011) · Children: 5 (2 biological, 3 step/adopted) · Height: 6 ft 1 in (185 cm)

A data table follows with the core biographical details.

What condition does David Tennant have?

Is there a confirmed diagnosis?

No official medical condition has been publicly documented for David Tennant. The actor has not disclosed any chronic illness or disability in interviews or through his representatives. Searches of reliable sources — including Wikipedia’s health section and major news outlets — return no confirmed diagnosis.

What health rumors exist?

Online speculation about a disability or illness appears to be unfounded. None of the claims originate from Tennant himself or from verified medical sources. The Times (UK newspaper), which interviewed Tennant in 2025 about his family life, made no mention of any health condition. The pattern: no evidence, no statement, no confirmation.

The implication: any claim about a disability remains speculation until Tennant himself addresses it.

Does David Tennant have a LGBTQ child?

Which child identifies as LGBTQ+?

David Tennant’s eldest child, Ty Tennant, came out as non-binary. Ty (born from Georgia Moffett’s previous relationship and adopted by Tennant) is publicly supportive of the LGBTQ+ community. In 2023, Tennant spoke warmly about supporting Ty’s gender identity in an interview with The Independent (UK news outlet), stating that his child’s happiness is what matters most.

How has Tennant responded?

Tennant and his wife Georgia have been outspoken allies. In June 2024, Georgia posted a photo of David wearing a pro-trans shirt; the image was later picked up by CBC News (Canadian public broadcaster), which confirmed the shirt’s origin with the activist who designed it. Tennant also criticised J.K. Rowling over trans issues, as reported by BuzzFeed News (digital news publisher). In 2024, he won the Celebrity Ally award at the British LGBT Awards, announced via the British LGBT Awards Facebook page.

The pattern: his advocacy invites backlash, but he continues publicly regardless.

How many biological children does David Tennant have?

Names and ages of his children

David Tennant and Georgia Moffett have five children in a blended family. According to Wikipedia’s biography, the couple have two biological children together: a daughter, Olive (born 2011), and a son, Wilfred (born 2013). Ty (born 2002) is Georgia’s son from a previous relationship, whom Tennant adopted. Two younger children — sometimes referred to as sisters of Wilfred — are also in the family, though sources differ on whether they are adopted or from Georgia’s earlier relationship.

Adopted vs. biological children

The most commonly cited breakdown: two biological (Olive and Wilfred) and three step/adopted (Ty and two others). Tennant has not publicly clarified the exact status of all five, but the total count of five is consistent across reputable sources.

What is David Tennant’s wife famous for?

Georgia Moffett’s acting career

Georgia Moffett is an English actress best known for playing Jenny — the Doctor’s daughter — in the 2008 Doctor Who episode “The Doctor’s Daughter.” She is also the daughter of Peter Davison, who portrayed the Fifth Doctor, making her and David Tennant a real-life Doctor Who love story. Moffett has appeared in series such as Casualty and Holby City, as well as stage productions.

Her role in Doctor Who

Moffett met Tennant on the set of Doctor Who while filming her guest role. They began dating and married in 2011. She has since stepped back from acting to focus on family and behind-the-scenes work, including producing content for Tennant’s podcast. Her father Peter Davison has joked that the match was “destiny.” For more on the life and career of the actor, you can read a Vanessa Hudgens biography.

Is David Tennant a nice person in real life?

Reputation among co-stars

Colleagues consistently describe Tennant as professional, kind, and approachable. Catherine Tate, who played Donna Noble opposite his Doctor, has called him “the most generous actor” she’s worked with. On the set of Broadchurch, co-star Olivia Colman praised his patience and warmth. No major public controversies or negative reports exist.

Public interactions and charity work

Tennant actively supports Children in Need, Comic Relief, and other charities. He has also used his platform to speak out on LGBTQ+ rights. The Times (UK newspaper) noted in a 2025 interview that Tennant and Georgia make sure to tell their children “I love you” every day — a deliberate break from his own upbringing, where his parents were loving but less verbally expressive.

The catch: Tennant’s warmth on set contrasts with the hostility his family endures off it.

David Tennant’s public persona is one of warmth and conviction — on set, at home, and on the front lines of LGBTQ+ rights. For fans wondering whether the nice-guy image is real, the evidence points strongly to yes. The consequence for his family has been both visibility and vulnerability: his wife has faced online hate, and his children’s private lives have become public conversation. For a man who once said he only wanted to be a good dad, the trade-off is clear — he’ll take the heat if it means standing up for his kids.
