Who Knighted the Most Named Characters? (Spoilers Extended)

Background

In this post I thought it would be fun to look into who knighted the most characters who GRRM has named in the series.

A similar post if interested: Body Count: Named Characters Killed by Individuals in Combat

Note: I couldn't find anyone else with more than 2 besides the below. We do get examples where there are mass knightings that include named characters that just aren't confirmed to who exactly did the knighting. For instance after the Blackwater the Kingsguard members knighted more than 600 men including named characters Bronn, and Osfryd/Osney Kettleblack and potentially Lothor Brune.

Beric Dondarrion = ~19

• The Knights of the Hollow Hill (there are ~19 named members who were likely knighted at some point)

Technically Beric has knighted the most (although it could be argued that they started knighting each other):

"The brotherhood without banners." Tom Sevenstrings plucked a string. "The knights of the hollow hill."

"Knights?" Clegane made the word a sneer. "Dondarrion's a knight, but the rest of you are the sorriest lot of outlaws and broken men I've ever seen. I shit better men than you."

"Any knight can make a knight," said the scarecrow that was Beric Dondarrion, "and every man you see before you has felt a sword upon his shoulder. We are the forgotten fellowship. -ASOS, Arya VI

and:

"I do, m'lord."

The marcher lord moved the sword from the right shoulder to the left, and said, "Arise Ser Gendry, knight of the hollow hill, and be welcome to our brotherhood." -ASOS, Arya VII

Rhaegar Targaryen = 3

• Myles Mooton
• Richard Lonmouth

Rhaegar knighted them (funnily enough, if Richard Lonmouth = Lem Lemoncloak the above entry should be ~18 for Beric):

"I make no such claim, ser. Myles Mooton was Prince Rhaegar's squire, and Richard Lonmouth after him. When they won their spurs, he knighted them himself, and they remained his close companions. -ASOS, Daenerys I

• Gregor Clegane

Gregor got his ointments too. Four years later, they anointed him with the seven oils and he recited his knightly vows and Rhaegar Targaryen tapped him on the shoulder and said, 'Arise, Ser Gregor.'" -AGOT, Sansa II

Robert Baratheon = 3

• Ser Hugh of the Vale

"Ser Hugh of the Vale," Littlefinger named him. "The king knighted the boy after Lord Arryn's death." -AGOT, Eddard V

• Jacelyn Bywater

"To be sure." Tyrion took a small sip of his own wine. "I had been considering Ser Jacelyn Bywater. He's been captain on the Mud Gate for three years, and he served with valor during Balon Greyjoy's Rebellion. King Robert knighted him at Pyke. And yet his name does not appear on your list." -ACOK, Tyrion II

• Jorah Mormont

The semi-canon app confirms that Robert did it:

When Robert's stonethrowers opened a breach in King Balon's wall, a priest from Myr was the first man through, but I was not far behind. For that I won my knighthood. -ACOK, Daenerys I

Aegon V Targaryen (Egg) = 2

• Barristan Selmy

From Barristan's white book entry:

Knighted in his 16th year by King Aegon V Targaryen, after performing great feats of prowess as a mystery knight in the winter tourney at King's Landing, defeating Prince Duncan the Small and Ser Duncan the Tall, Lord Commander of the Kingsguard. -ASOS, Jaime VIII

• Tywald Lannister

From the (unabridged) version of The Westerlands:

Tywald, the eldest of the twins, died in battle in 233 whilst squiring for Lord Robert Reyne of Castamere during the Peake Uprising.  Pierced through with a spear as he clambered through the broken gates of Starpike, Tywald died in the arms of his twin brother Tion, who was serving as a squire to Prince Aegon Targaryen, King Maekar’s youngest son.  The prince, it is said, fulfilled Tywald’s last request, and dubbed him a knight as he was dying. -TWOIAF, The Westerlands

Barristan Selmy = 2

• Red Lamb
• Tumco Lho

Ser Barristan took two of his new-made knights with him down into the dungeons. Grief and guilt had been known to drive good men into madness, and Archibald Yronwood and Gerris Drinkwater had both played roles in their friend's demise. But when they reached the cell, he told Tum and the Red Lamb to wait outside whilst he went in to tell the Dornish that the prince's agony was over. -ADWD, The Queen's Hand -ADWD, The Queen's Hand

TLDR: Just a quick list of some of the characters who have knighted some of the most characters that GRRM has given names to.
