Holm's first marriage was at age 19 to Ralph Nelson in 1936.
The marriage ended in 1939.
Their son, Internet pioneer and sociologist Ted Nelson (born 1937), was raised by his maternal grandparents.
In his 2010 memoir, Possiplex, her son, credited with coining the term "hypertext," described this and other choices as "entirely the right decisions."
He reportedly did not name his mother in the book.

Holm married Francis Emerson Harding Davies, an English auditor, on January 7, 1940.
Davies was a Roman Catholic, and she was received into the Roman Catholic Church for the purposes of their 1940 wedding; the marriage was dissolved on May 8, 1945.

From 1946 to 1952, Holm was married to airline public relations executive A. Schuyler Dunning, with whom she had a second son, businessman Daniel Dunning.

In 1961, Holm married actor Wesley Addy.
The couple lived together on her family farm in Washington Township, Morris County, New Jersey.
He died in 1996.

On April 29, 2004, her 87th birthday, Holm married opera singer Frank Basile, who was 41 years old.
The couple met in October 1999 at a fundraiser for which Basile was hired to sing.
Soon after their marriage, Holm and Basile sued to overturn the irrevocable trust that was created in 2002 by Daniel Dunning, Holm's younger son.
The trust was ostensibly set up to shelter Holm's financial assets from taxes though Basile contended the real purpose of the trust was to keep him away from her money.
The lawsuit began a five-year battle, which cost millions of dollars, and according to an article in The New York Times, left Holm and her husband with a "fragile hold" on their apartment, which Holm purchased for $10,000 cash in 1953 from her film earnings, and which in 2011 was believed to be worth at least $10,000,000.
