Maisie Lockwood Sr. (S/F)

Maisie Lockwood, Sr. (August 15, 1983 – June 31[?], 2008) was the daughter of Sir Benjamin Lockwood and the mother of Maisie Lockwood, Jr. She passed away due to a car accident at the age of twenty-four.


Maisie is a given name of Scottish origin; it is a diminutive form of the English name Margaret, which means “pearl.” The surname Lockwood is Anglo-Saxon in origin and is a habitational surname: that is, it originates from the name of a place, specifically a village in what is now a suburb of Huddersfield in West Yorkshire. All people who bear the surname Lockwood are descendants of a single family that lived in this village. It is an old name, dated as far back as the seventh century CE.

Maisie Lockwood is not referred to by the suffix Senior because her daughter (who bears the same name) was not born until at least nine months after she died and lacks official public records. Jurassic-Pedia has appointed both Maisie Lockwood Sr. and Jr. with these suffixes to differentiate between them.

Early life

Maisie Lockwood, Sr. was born on August 15, 1983 to a wealthy British family. She was most likely born at the Lockwood estate near Orick, California, USA, as her father Sir Benjamin Lockwood was living in the United States for business purposes. Her mother’s name is currently undisclosed.

Lockwood Manor’s caretaker, Iris Carroll, played a major role in Maisie’s childhood. Carroll’s commentary later in life describes her as a strong maternal figure.

Though she was greatly adored by her father, he was often away on business. The young Maisie eventually learned that his work with International Genetic Technologies on faraway Isla Nublar was in pursuit of de-extinction. Her father had researched this within their home’s sub-basement laboratory with his business partner Dr. John Hammond and paleogeneticist Dr. Laura Sorkin during 1985 when Maisie would have been two years old. With the added help of Dr. Henry Wu in 1986, her father oversaw the creation of their first de-extinct animal, a Triceratops horridus, on the island of Isla Sorna.

Sometime before 1993 or in the early months of that year, Maisie was brought to Isla Nublar by her father to see the fruit of their labors, a theme park called Jurassic Park. According to her father’s account, Maisie was excited and intrigued by the dinosaurs. She was the Park’s first known guest to visit for non-business purposes.

However, her family’s involvement with Jurassic Park would come to an end not long after her visit to the island. Her father believed that InGen’s advanced cloning technology could be used for more than just de-extinction. He proposed human cloning, which could be used for research, stem cell therapy, and other medical purposes. Hammond vehemently disagreed, and this controversy destroyed the men’s friendship. They parted ways before the summer of 1993, at which point Maisie would have been almost ten years old. That summer, Jurassic Park experienced two serious safety incidents, the second of which delayed the Park’s opening indefinitely.

Throughout the mid-1990s, rumors and conspiracies about a de-extinction theme park spread throughout the public but were largely dismissed as a hoax. In 1997, when Maisie was a young teenager, de-extinction became public knowledge. A buck tyrannosaur was accidentally released into the streets of San Diego, California before being safely returned to Isla Sorna with its son. Within a year of this revelation, InGen was bought by Masrani Global Corporation.

The age of Jurassic World

Maisie would have been a few months shy of twenty-two years old when Jurassic World opened on Isla Nublar on May 30, 2005. By this time, her father was beginning to seek involvement with InGen again, his memory of Hammond having softened after the latter’s death on New Year’s Day in 1998. Because of her history with Jurassic Park, and her childhood interest in dinosaurs (which her father surely encouraged), there is a good chance that she visited Jurassic World at some point during its operation.

It is not known where Maisie lived during this period of time. She may have remained with her family near Orick, or moved elsewhere to start a life of her own. According to the Jurassic World: Fallen Kingdom junior novelization, she was married to a man as of 2008.

Death and legacy

In 2008, a month and a half before her twenty-fifth birthday, Maisie Lockwood and her husband were involved in a fatal vehicular accident. Details about the accident are undisclosed at the moment; it is not known who was at fault, or whether she was a driver or passenger. Records state that she passed away on June 31. This is most likely meant to indicate June 30, since the month of June has only thirty days.

Invitation to Maisie Lockwood’s celebration of life

The Lockwood family was distraught at their only daughter’s death. Her father took this particularly hard, grieving her severely. On June 5, only a few days after her death, Maisie Lockwood’s celebration of life was held at St. Anne’s Church, presumably the one in Sacramento, California, since this would have been the closest church by that name to the Lockwood estate.

Her father’s mourning drove him toward InGen’s technology for a solution. Using his deceased daughter’s DNA, Lockwood performed the first confirmed case of human cloning for reproductive purposes. His “granddaughter,” also named Maisie, was born sometime before mid-June of 2009, roughly a year after his daughter’s death.

Social skills

Her father described Maisie Lockwood, Sr. as having a “wicked” sense of humor. She appears to have been well-loved by those who knew her, particularly her father and her caretaker Iris Carroll.


Because she died in a car crash, it is possible that Maisie possessed a valid U.S. driver’s license as of 2008. However, is is also possible that she was a passenger in the crash.

On de-extinction and animal rights

Because little is known about her life, her views on any topic are taken from anecdotal sources. Her father recalls her as having a great love for dinosaurs; according to Sir Benjamin, had Maisie been alive during the Mount Sibo controversy of 2017-2018, she would have advocated for the rescue of the animals. This suggests a generally positive outlook on de-extinction, which her father probably influenced.


Maisie was adored by her father, Sir Benjamin Lockwood, who even took her to the secretive Jurassic Park construction site on Isla Nublar at one point. Lockwood was severely distraught by her death in 2008. He turned to extreme measures to cope, going so far as to create a clone of his daughter to fill the emotional void she left behind.

Her relationship with other family members are less known. Little has been said of her mother; some photographs in the Lockwood family album appear to show her playing with her grandmother at a very young age.

Maisie Sr. never met her daughter, owing to the fact that Maisie Jr. was cloned after her death. She was married as of her death according to the junior novelization, but she did not have any children while she was alive.

Manor staff

At the Lockwood estate, Maisie’s closest relationship outside of her own family was with the mansion’s caretaker Iris Carroll. According to Carroll’s own account, she acted as a maternal figure to Maisie (a role she resumed for Maisie Lockwood, Jr.). Although Carroll has a stern demeanor, she expresses very fond memories of Maisie Sr. and was one of extremely few people Sir Benjamin trusted with the safety and wellbeing of Maisie Jr.

It is unknown whether Eli Mills had begun working for Benjamin Lockwood by 2008, at the time of Maisie Sr.’s death. Other staff members at the estate, such as Lockwood’s chauffeur, may have known her prior to her death, depending on how long they worked there.

Isla Nublar animals

During her childhood, Maisie was brought to Isla Nublar by her father to see the in-construction Jurassic Park and its de-extinct inhabitants. According to her father’s account, she was thrilled by the dinosaurs. It is not known which animals she personally encountered; by June of 1993, there were at least eight species (Triceratops, Brachiosaurus, Tyrannosaurus, Parasaurolophus, Dilophosaurus, Gallimimus, Velociraptor, and Herrerasaurus, as well as possibly Pteranodon) actually on display. Others, including Troodon, Tylosaurus, and Compsognathus, were not on the island in “official” capacity, so she probably did not witness these. Depending on when she went to the island, some of the official species may not have been present yet. For example, Herrerasaurus was among the newest additions to the Park as of June 1993, so Maisie probably did not encounter them as her visit would have been before this.

It is not known whether she returned to the island as a young adult during the period between Jurassic World’s opening day in 2005 and her death in 2008. If she did, she would have seen not only some of the animals from the old Park, but dozens of new ones as well.

According to her father, Maisie cared about dinosaur welfare and would have supported their status as endangered animals deserving of rights.


Few photos exist of Maisie Lockwood Sr. and she is not portrayed directly in any of the films. She is not based on any character in Michael Crichton‘s novels.

In one photo depicting a nine-year-old Maisie Sr., she is portrayed by Isabella Sermon, who also portrays Maisie Lockwood Jr. in the films. An unused image of an invitation to Maisie Sr.’s celebration of life uses the image of an uncredited photo model to represent her as a young adult.
