Lily L. Potter

Lily Luna Potter (born between 1 September, 2007 and 31 August, 2008) was the only daughter and the youngest child of Harry and Ginny Potter (née Weasley). She had two older brothers; James Sirius and Albus Severus. She was named for her paternal grandmother and also her parents' good friend, Luna Lovegood.

Biography
Lily Luna Potter was born to Harry and Ginny Potter as their youngest child and only daughter. She has two older brothers: James Sirius and Albus Severus Potter. Lily is around two years younger than Albus, who is at least a year younger than James. Her godparents are also her aunt and uncle, Hermione and Ron Weasley.

In 2017, she went to see her brothers and her cousin, Rose Weasley, off at the Hogwarts Express, but was not herself old enough to attend Hogwarts School of Witchcraft and Wizardry. She also acted as excited and enthusiastic as her mother Ginny had acted when Harry and Ron went to their first year of Hogwarts. She and her cousin, Hugo Weasley, are around the same age.

Physical appearance
Lily is described as having red hair. Lily does not have the green, almond-shaped eyes of her father, so it's likely she may have her mother's brown eyes. Lily takes after mostly her maternal family (and her paternal grandmother) in looks, rather than her older brothers, who take after their paternal family.

Personality and traits
Lily seems to have a personality similar to her mother. She is very jealous of her two older brothers when they are leaving for Hogwarts, quite similar to the eagerness and envy Ginny displayed when the last of her brothers went away to school in 1991. She seems to enjoy talking to her family. She and Hugo, her cousin, had an "animated discussion" about what house they would be in, suggesting they are really close cousins.

Parents
Lily is shown as having a close relationship with her father and her mother; she resembles her mother, Ginny Weasley in appearance and personality. She also seems to love her father dearly, and was holding hands with him in 2017.

Siblings and cousins
James seemed to have a fondness for teasing his younger siblings. Lily went to see her brothers off at the Hogwarts Express in 2017. Lily seems to be close with her brother James Sirius and seems to be holding his hand at Kings Cross Station through the barrier.

Hugo, Rose, and Victoire Weasley are probably the cousins Lily is closest to. In addition to being the same age, she and Hugo excitedly discussed Hogwarts in 2017. Lily was thrilled when she heard about the relationship between Victoire and Teddy Lupin, mentioning that if they married, Teddy would formally become part of their family.

Teddy Lupin
Teddy Lupin was Lily's father's godson. He often spent time at the Potters' home, and Lily was very excited at the news that he was dating her cousin Victoire. She hoped that they might marry so that Teddy would become an official member of the family. This is very similar to Ginny's longing to have Nymphadora Tonks, Teddy's late mother, in her family, deepening the connection between Lily and her mother.

Etymology

 * The given name Lily comes from the name of the flower, which is a symbol of purity. Specifically, the lily is often associated with the Virgin Mary; one type of the flower is known as the Madonna lily. Greek mythology also links lilies to the Muses and to the goddess Hera, and the flowers continue to be representative of purity and love in Europe. In Chinese, lily is a play on words for "forever in love", and the flowers were thought to be capable of averting evil.
 * Luna means "Moon" in Latin. It is also the name of the Ancient Roman goddess of the moon who was the mother of the Menae, fifty goddesses who embodied the phases of the moon used by the Ancient Greeks to keep time. In some myths, she was also the mother of the Nemean Lion.
 * Potter is a very common surname of English origin. It traditionally refers to the occupation of making pottery. Beatrix Potter was a well-known English children's author. Potter's Field is the name for a burial ground for the unknown or unclaimed dead, particularly soldiers and orphans; the Potter family had many members that fit that description. The Potter Box is a model for making ethical decisions developed at Harvard University.

Behind the scenes

 * Daphne de Beistegui portrays Lily Potter in Harry Potter and the Deathly Hallows: Part 2.
 * Lily was the first of Potters' children to be introduced in the epilogue, where she was shown holding her father's hand, much as her mother (Ginny) was introduced in Harry Potter and the Philosopher's Stone.
 * She is the only child of Harry and Ginny who was named after a living person at the end of the series. Luna still lived while James, Lily, Sirius, Dumbledore, and Snape all had died.
 * Lily is one of the only three children (the other two being her older brothers) who can call Molly and Arthur Weasley their maternal grandparents and Bill, Charlie, Percy, Fred, George, and Ron Weasley their maternal uncles, as their mother was the only daughter of Molly and Arthur. All of her other cousins are related to the Weasley family by their father, making the Weasleys their paternal family.
 * Lily takes after her maternal family and paternal grandmother while Albus takes after their paternal family.
 * Lily, her eldest brother, her cousin Molly, and her cousin Fred are the only Weasley grandchildren to be named after a relative. Lily was named after her grandmother, Lily Evans, Molly was named after her paternal grandmother Molly. Fred was named after his late uncle, and James was named after his paternal grandfather.
 * Lily is, like her mother, the first girl to be born into their respective families in a number of generations. While Ginny was the first girl to be born into the Weasley family in several generations, Lily was the first female to be born in the Potter family in at least three generations, due to Lily's father and paternal grandfather both being only children. Like Ginny, this may (at least partially) mark her as a powerful witch.
