Who Are Her Parents?
Her dad is Alec Baldwin, the actor known for his long film career and his years on Saturday Night Live and 30 Rock.
Her mom is Hilaria Baldwin, who was born Hillary Lynn Hayward-Thomas in Boston, Massachusetts. She works as a yoga instructor, author, and podcast host, and she married Alec Baldwin in June 2012.
Together, Alec and Hilaria have raised their seven kids in a bilingual home, with both English and Spanish spoken day to day.
What Does Her Name Mean?
Hilaria explained the meaning behind her daughter’s name in an Instagram post shortly after she was born.
“Ilaria” is a close match to her mom’s own name, Hilaria, and both names mean “happy” across different languages. The middle name “Irena” is a tribute to her mom’s side of the family. Hilaria wrote that she wanted her daughter’s name to carry a message of happiness and strength passed down through the women in the family.
Great-Grandparents and Family Roots
On her mother’s side, Ilaria’s family tree traces back through the Hayward and Thomas families of the Boston area. Her mom has spoken about family history and heritage in interviews and on social media over the years.
On her father’s side, she is connected to the wider Baldwin family, including her dad’s siblings Stephen Baldwin, William “Billy” Baldwin, and Daniel Baldwin, who are also actors.
Is Alec Baldwin Her Father?
Yes. Alec Baldwin is her biological father, and Hilaria Baldwin is her biological mother. Ilaria is their seventh child together.
Alec also has an older daughter, Ireland Baldwin, from his first marriage to actress Kim Basinger. That makes Ireland Ilaria’s older half-sister, even though there is a big age gap between them.
Does She Appear on TV?
Yes, in a way. Ilaria has appeared alongside her family in “The Baldwins,” a reality series on TLC that follows the day-to-day life of the Baldwin household. Since she is one of the youngest kids in the family, she shows up in family scenes rather than carrying storylines of her own.
How Many Siblings Does She Have?
Ilaria has six siblings from her parents’ marriage: Carmen, Rafael, Leonardo, Romeo, Eduardo, and María Lucía. She also has one older half-sister, Ireland Baldwin, from her dad’s first marriage.
That brings her total sibling count to seven, making her the youngest of eight children altogether on her father’s side.
