Charlotte Harmon Eggar is best known publicly as Demi Moore’s paternal half-sister. The two women share the same biological father, Charles Harmon Sr., but grew up separately. Charlotte has remained largely outside the entertainment spotlight, while Moore went on to become an internationally recognized actress and producer.
Reliable information about Charlotte herself is limited. Her name has appeared in reporting about Demi Moore’s family, including a 2012 OK! report in which Charlotte spoke about her famous half-sister. Beyond those documented family connections, many biographical details circulating online are difficult to independently verify.

Early Life and Family Background
Charlotte Harmon Eggar is identified in genealogy records as a daughter of Charles Harmon, making her a paternal half-sibling of Demi Moore. MyHeritage’s biographical record for James Craig Harmon lists Charles Harmon as his father and names both Demi Moore and Charlotte Harmon Eggar among his siblings.
Demi Moore was born Demi Gene Guynes on November 11, 1962. Her biological father was Charles Harmon, an Air Force serviceman who was not involved in raising her. Moore was subsequently raised by her mother, Virginia, and stepfather, Dan Guynes.
Charlotte and Demi therefore shared a biological father but did not grow up as sisters in the same household.

Charlotte Harmon Eggar and Demi Moore
Charlotte’s relationship with Demi became publicly documented in 2012, when OK! reported on Demi’s family members reaching out to her during a difficult period in the actress’s life.
According to the report, Charlotte first met Demi when Demi and her mother, Virginia Guynes, visited Charles Harmon in Houston, Texas. Charlotte recalled the meeting and said she remembered Demi as already being ambitious and having the potential to become famous.
The same report said the families later became separated and that Charlotte and Demi lost contact. Charlotte said at the time that she had not seen her half-sister in roughly three decades.
That account provides one of the clearest publicly available descriptions of the sisters’ relationship. It also illustrates why Charlotte’s name occasionally appears in coverage of Moore’s family despite her own largely private life.
Career and Public Life
There is not enough reliable evidence to establish Charlotte Harmon Eggar’s profession.
Several websites describe her as a journalist, broadcaster or media professional, but those claims are not supported by sufficiently strong independent evidence such as verified professional records, established publications or documented broadcasting credits. They are therefore not presented as fact.
Charlotte has not established a public entertainment career comparable to Demi Moore’s. Her public visibility comes almost entirely from her family connection to the actress and from her comments about their relationship.
Personal Life
Charlotte Harmon Eggar has generally remained outside the public eye.
Reliable sources do not establish a detailed account of her marriage history, children, education, residence or current occupation. Some websites publish highly specific claims about these subjects, but the information is not sufficiently corroborated to include as established biography.
Her privacy also means that the public record provides considerably more information about her connection to Demi Moore than about Charlotte’s own day-to-day life.
Demi Moore’s Family Connection
Charlotte is one of several half-siblings associated with Demi Moore’s family tree.
Public genealogical records identify Charles Harmon Jr. and James Craig Harmon as paternal half-brothers of Demi and Charlotte. Moore also has a maternal half-brother, Morgan Guynes.
This family structure helps explain the distinction between Moore’s biological and immediate family relationships. Charlotte shares their father but not Moore’s mother, Virginia.
Net Worth
There is no credible, publicly verified estimate of Charlotte Harmon Eggar’s personal net worth.
Because her professional activities and financial circumstances are not reliably documented, online figures claiming a specific fortune should not be treated as established fact.
