Alec is married to fitness and wellness expert Hilaria Baldwin.

Alec was raised in the Roman Catholic faith.

He was the host of the show Up Late with Alec Baldwin in 2013.

Alec’s patrilineal line traces back to a Richard Baldwin, who lived in England, c. the 1500s. His father was of English, Irish, and Scottish ancestry. His mother was of French-Canadian, English, Irish, German, and Scottish ancestry.

Alec’s paternal grandfather was Alexander Rae Baldwin (the son of Sylvester Davis Baldwin and Helen Irene McNamara). Alec’s grandfather Alexander was born in New York. Sylvester was the son of Roswell C./B. Baldwin, who was of Colonial American (English) descent, and of Hannah Miles, who was born in England. Helen was also born in England, to Irish parents, James McNamara and Mary O’Connor.

Alec’s paternal grandmother was Ruth Mary Noble (the daughter of Leveret/Leverett David Noble and Lena Xea McCauley). Ruth was born in New York. Leveret was born in New York, the son of Daniel McCormick Noble, who was born in New York, to Scottish parents, and of Jane Watson, who was from Yorkshire, England. Lena was born in Moose Creek, Ontario, Canada, and likely had Irish roots.

Alec’s maternal grandfather was Daniel Leroy Martineau (the son of Henry Frazier Martineau and Ada Emmaline Newcomb). Daniel was born in New York. Henry was of approximately half French-Canadian and half English ancestry, and was the son of Joseph Martineau, who was born in Canada, and of Emma Laura Parsons. Ada had English ancestry, and was the daughter of Daniel Webster Newcomb, who was born in New York, and of Emeline Fay Crawford, who was from Brantford, Ontario, Canada.

Alec’s maternal grandmother was Marion Alice Sidnam (the daughter of Irving Albert Sidnam and Mary Louise Haas). Marion was born in New York. Irving was the son of David A. Sidnam and Almida Osborne. Mary Louise was the daughter of Francis Xavier Haas, who was German, and of Alice McKenna, who herself was the daughter of James Baron McKenna and Catherine Dunn, and had Scottish and Irish ancestry.

Why? It has very little information and is almost totally useless.

andrew June 20, 2016 at 4:51 pm

yes, it’s partial. Some lines are well documented though.

He is the doppelganer of my uncle and I have people with the surname Baldwin in my family.

gel March 25, 2015 at 3:18 pm

Whatever – he LOOKS Irish, blue eyes and all.

follers March 25, 2015 at 3:39 pm

I think someone should break it to you that blue eyes are common among a large number of ethnic groups other than Irish. Nor are blue eyes indigenous to Ireland.

gel August 14, 2015 at 8:02 am

They are. Certainly NOT English.

I was in England and a woman said to me “I bet you’re Irish”.(I don’t look unlike Baldwin, dark hair, blue eyes!).
Then I realized a few things!

A user August 14, 2015 at 12:32 pm

What the hell is it with you and irish people having blue eyes.

Wrong. He is very English. I mean his damn last name is ENGLISH.

andrew December 8, 2013 at 5:48 pm

you can’t be English and Catholic. I think the Baldwins are culturally more Irish than English

archer December 22, 2013 at 1:11 pm

Of course you can be. It’s not 1550 anymore, you know.

His daughter, Ireland Baldwin, is very pretty. He had her with his ex-wife, Kim Basinger.

BUU January 17, 2012 at 5:39 pm

Dude you wrong. In Wiki of his early life it explain that he is French, Irish, and English even Alec Baldwin mention it.

Dude September 23, 2010 at 2:01 pm

Wrong. Very English as his family is Mayflower and French-Canadian not French American.
