Gil-galad did not take a wife and had no children. He was the first of the Eldar to mistrust a stranger who called himself Annatar, and forbade him from entering Lindon.
Thus he became the first High King of the Noldor in Middle-earth. Let's skip a couple thousand years: Gil-galad is killed in combat by Sauron, leaving no heir. There were still some Elves from the House of Finwë in Middle-earth: Elrond and Galadriel.
What is the relationship between Gil-galad and Galadriel?
Gil-galad is the GRANDSON of Galadriel's brother, Angrod. So Galadriel is Gil-galad's Great-great aunt. Her hair shine with the light of the Two Trees of Valinor which where destroyed more than a millenium and a half before his own birth.
Elves in Middle-earth rarely have children because it takes a great deal of thought and consideration. Elven children age slowly and mature at 100, which means they have a longer period to grow. Arwen's choice to have children with Aragorn reflects the Elven race's careful approach to parenting.

What happened to Francesca's baby?
In an attempt to impress Emhyr, Cahir and Fringilla claimed credit for killing Francesca's child and turning the elves against their enemies in Redania. However, they didn't realize that it was actually Emhyr who had the child killed.
Based on Galadriel's age, exposure to the trees, her deeper connection to the Ainur and Tolkien's descriptions, she most likely possessed greater power than Gil-Galad in terms of magical, otherworldly, fearsome presence. Leading an army or engaging in a physical fight, Gil-Galad may fare better.
Celebrimbor, the creator of the Three Rings, gave two of them, Narya and Vilya, to Gil-galad for safe-keeping once he knew Sauron's intention to take them.
It is a reward of high honor for Galadriel and her team of soldiers, as a recognition for their bravery in chasing the evil Sauron into the North to discover if his poison and malice still existed in the world.
Even though Gil-galad ruled over the Ñoldor in Middle-earth as their High King, he was actually younger than another star character in the show, Galadriel. She was actually what we would call his great aunt, and she was vastly more powerful as a magic user than Gil-galad.
Unfortunately, Gil-galad's death scene was cut, but the creative choice does make sense. As Gil-galad actor Mark Ferguson explains in this YouTube video, it made little sense to focus on the Elven king when he was simply going to die. Instead, the final cut made it seem like Elrond was in charge of the Elvish army.
After the War of the Last Alliance and the death of Gil-galad, Círdan ruled over Lindon from the Grey Havens. For more than a thousand years they went undisturbed, but at around TA 1050, a shadow began to lengthen.
Gil-galad was the last heir of the kings of the Noldor in exile, and acknowledged as High King of the Elves of the West. Many Elves, both the Sindar and the Noldor, joined him. But soon, there was again unrest among the Noldor, and many of them left Lindon.
What is the relationship between Gil-galad and Elrond?
No. He was Gil Galad's herald in his army. Elrond and his twin Elros were born of Earendil and Elwing, and were the great grandchildren of Beren and Luthien thus the half elven attachment.
There are many secondary reasons that Elrond received Vilya, such as the fact that he was Gil-Galad's herald and second-in-command, and Galadriel already possessing Nenya before Gil-Galad's passing, but the primary reason is because Elrond is Gil-Galad's heir.
Gil-galad wanted mithril because the Light of the Eldar was fading in Middle-earth, and the Elves along with it. They required the light of the Silmarils to save themselves, but they never needed to look underground for salvation.
Elrond's powers are great, to be sure, but Galadriel is simply in a class of her own, and is definitely the being who is greater in power between the two of them.
In The Lord of the Rings, it is said that had Galadriel chosen to use her powers for evil instead of good, she would have been even more destructive and terrifying than Sauron himself. Galadriel was the greatest and most powerful of all Elves in Middle Earth in the Third Age.
While Glorfindel already one of the greatest of all elves as Ecthelion and Glorfindel are Gondolins greatest captains. So in the first age Feanor is the most powerful elf. In the second age it's Galadriel. In the Third age it's reincarnated Glorfindel.
Tolkien's elves are immortal and only rarely have children, which means they wouldn't have regular periods. D&D's elves are as mortal as humans and just live longer, and can have half-elf children with humans, which implies its elven babies are made the same way as human babies and with similar biological rhythms.
At what age do elves stop aging in Lord of the Rings?
Unlike the race of Men, they didn't physically age. They just remained constant -- an unchanging incarnation of their eternal form. Thus, once they were 100 years old, they looked the same for the rest of their lives. While Elves were done growing at 100 years old, they never stopped growing mentally.
Are any of the elves who first awoke Cuiviénen still around by the time of LOTR? The oldest elf in LoTR is Círdan the Shipwright, the oldest Elf still remaining in Middle-Earth, who appears at the end of Return of the King to sail to Valinor.
