Quick Scoop: Sean McDermott’s Kids

From multiple recent profiles and features on Sean and his wife Jamie, the couple are described as parents of three children: Madelyn (often “Maddie”), Gavin, and Kelly.

• Madelyn/Maddie is the eldest daughter, reported as born in 2010.

• Gavin is the middle child, reported as born in 2012.

• Kelly is the youngest daughter, reported as born in 2017.

Given those birth years, as of early 2026 their approximate ages would be:

• Madelyn/Maddie: about 15–16 years old (depending on her 2010 birth month).

• Gavin: about 13–14 years old.

• Kelly: about 8–9 years old.

These are approximations , since month-and-day birthdays are not consistently published in mainstream coverage, but the 2010 / 2012 / 2017 timeline appears across reputable outlets.
