Marilyn Monroe was an American actress, model, and singer. Her half-sister is author Berniece Baker Miracle.
Marilyn’s mother, Gladys Pearl (Monroe), had English, as well as Scottish, Irish, and Welsh, ancestry. A DNA test of a relative of Marilyn’s maternal grandfather established Marilyn as a descendant of a soldier from the area around Tain, Scotland, who was exiled to America after the English Civil War, in the mid-17th century. Marilyn’s stepfather was John Newton Baker.
Norma’s mother listed her ex-husband, Martin Edward Mortensen, as Marilyn’s biological father on her birth certificate, though they had been separated for some time. It is not clear if Martin was Marilyn’s biological father. Marilyn’s mother later told her that her biological father was Charles Stanley Gifford. Marilyn talked about this in her autobiography My Story, published in 1974. Martin Mortensen was the son of Martin Mortensen, from Stavanger, Stavanger, Rogaland, Norway, and of Catherine “Katie” Higgins, from Kansas City, Jackson County, Missouri. Charles Stanley Gifford, who was from Newport, Rhode Island, had English, Scottish, French, and Irish ancestry, and was the son of Frederick Almy Gifford and Elizabeth Easton Tennant. A genealogy of Charles can be seen here.
Monroe converted to Judaism before her marriage to playwright Arthur Miller, in 1956. She practiced Judaism after their divorce.
Marilyn’s maternal grandfather was Otis Elmer Monroe (the son of Jacob Monroe and Mary E. Appleton). Otis was born in Indiana. Jacob was the son of William Monroe and Mary C. Marilyn’s great-grandmother Mary was the daughter of James Appleton and Elizabeth Jane Smith.
Marilyn’s maternal grandmother was Della/Delia Mae Hogan (the daughter of Tilford Marion Hogan and Charlotty/Charlotte Virginia “Jennie” Nance). Della was born in Missouri. Tilford was the son of George Washington/Willis Hogan and Sarah Ann/Anne Owen/Owens. Charlotty was the daughter of Levi Nance and Sarah Caroline Jones.
