Justin Theroux

Birth Name: Justin Paul Theroux

Place of Birth: Washington, D.C., U.S.

Date of Birth: August 10, 1971

*French-Canadian (paternal grandfather)
*Italian (paternal grandmother)
*English, with more distant German, and even more distant Spanish and Dutch (mother)

Justin Theroux is an American actor, film producer, comedian, and screenwriter.

Justin is the son of Phyllis Theroux, an essayist and author, and Eugene Albert Theroux, a lawyer. His uncles are travel writer and novelist Paul Theroux, novelist and poet Alexander Theroux, author Peter Theroux, and novelist and educator Joseph Theroux. His cousins are journalists and documentary filmmakers Louis Theroux and Marcel Theroux. Justin is married to actress Jennifer Aniston.

Justin’s father is of half French-Canadian and half Italian descent. Justin’s mother is of mostly English ancestry; Justin is also of 1/32 German, 1/128th Spanish, and remote Dutch, descent, through his mother.

Justin’s paternal grandfather was Albert-Eugene Theroux (the son of Joseph-Louis-Eugene Theroux and Eva-Almira Brousseau). Albert-Eugene was born in Massachusetts, of French-Canadian descent. Joseph-Louis-Eugene was the son of Pierre Theroux and Marie Catherine Eugenie L’Oiseau-Cardin. Eva-Almira was the daughter of François-Xavier Brousseau and Delphine/Delphina Picard/Pecor.

Justin’s paternal grandmother was Annina/Anna/Anne Francesca/Frances Dittami (the daughter of Alessandro/Alexander Louis Dittami and Angelina/Angela M. Calesa). Annina was born in New York, of Italian ancestry. Alexander was from Ferrara, Emilia-Romagna, Italy. Angelina was from Piacenza, also in Emilia-Romagna, and was the daughter of Francesco Bonifacio Calesa and Ermengilda Buongioni.

Justin’s maternal grandfather is John de Lafayette Grissim (the son of John de Lafayette Grissim and Irene Baker). Justin’s grandfather John was born in California. Justin’s great-grandfather John was the son of John DeLafayette Grissim and Hannah Annette Ransdale Moore. Irene was the daughter of George Washington Baker and Mary Agnes Hall.

Justin’s maternal grandmother is Phyllis Hollins (the daughter of Gerald Vanderbilt Hollins and Virginia Kobbé). Phyllis was born in New York. Gerald was the son of Harry Bowly/Bowley Hollins, a financier, and of Evelina Merseole Knapp. Virginia was the daughter of Gustav Kobbé, a music critic and author, and of Carolyn Wheeler. Gustav’s father was a German immigrant, and one of Gustav’s maternal great-grandfathers, Gabriel Sistare, was a Spanish immigrant, thus making Justin Theroux of 1/32 German and 1/128th Spanish descent (through those lines).

he looks so british

like ROBBIE WILLIAMS or old james bond actors

Capricious October 8, 2015 at 6:28 am

He’s cute, but he shouldn’t dye his hair black. It’s obvious that he has brown hair. I think he even dyes his eyebrows…?

neiltennant August 8, 2015 at 10:10 am

italian roots are strong

cwm85 August 7, 2015 at 1:12 pm

French and Italian. Nice. His surname was a dead give away for some of his ancestry. Cool about others. I wonder if he and his wife will have kids now?

WTF November 11, 2014 at 3:44 am

Wtf why do y’all choose the UGLIEST pictures of people? He actually isn’t that bad looking, but of course his picture on here is ugly as hell.

anen87 May 21, 2013 at 6:54 pm

Anyone find the fractions references smaller than 1/8 creepy? I mean who talks like that anyways?

I think its a good way of describing how much of a certain heritage a celeb has for those who are curious.

andrew May 21, 2013 at 12:55 pm

HOW is this guy a celebrity??? Just because you date someone famous that doesn’t make you a celebrity. This is like Jessica Alba’s husband…why is he on here?! His wife is an actress, he’s just a behind the scenes person…smh.

The Fox August 30, 2011 at 1:26 pm

He is an actor, and he has been for years. You just made yourself look very stupid.


Islander_Miss September 5, 2011 at 10:05 pm

Well, excuse me! I still didn’t know his name before he started Jennifer Aniston. You don’t have to be immature..smh. Just because I don’t know everything about all the people on these lists. I stand by my statement about Jessica Alba’s husband.

Midnight September 6, 2011 at 4:06 pm

Hey, well I’m stupid too because I expected to se a biracial Black and French dude lol. He’s not that famous. I’m an old Hollywood fan and people today don’t interest me quite as much(as a fan). I’ve see Jessica Alba a hand full of time but she’s not interesting to me either. I can watch Paul Newman and Robert Mitchum all day. Don’t get me started on Charles Bronson.

Islander_Miss September 7, 2011 at 7:42 pm

thanks, appreciate that, hehehe. I’m not a big Jessica Alba (I was actually talking about her husband though) fan either. I mean, she’s gorgeous, but until she does a movie with some substance then is all “ehhh”.

I honestly didn’t know he IS an actor. the extra messed up thing is I watched Your Highness a few weeks ago! =/ I didn’t know that was him…I wasn’t looking at the credits. besides, I was only watching it for James Franco & Danny McBride, they are funny!

People who comment on this site need to chill…it’s the internet, gees!

his most famous work was the guy in the MUSE video of HYSTERIA

Tyler Durden March 5, 2016 at 6:13 am
