The 212th Attack Battalion was a subdivision of the larger 7th Sky Corps led by Commander Cody and Jedi General Obi-Wan Kenobi during the days of the Clone Wars.
212th specialized troopers are the only clones with markings during the Battle of Christophsis arc. In the episode "Legacy of Terror", the squad of elite troops Kenobi takes is entirely of the 212th, with painted colors nonetheless to distinguish them.
Telling Anakin to stay behind, Windu and three other Jedi Masters (Kit Fisto, Saesee Tiin and Agen Kolar, the former 2 of whom were initially meant to die in Order 66) try to arrest Sidious, but the Sith Lord easily cuts down Windu's companions and then duels him one-on-one.
Billaba became Windu's Padawan and trained under the Jedi Master in the ways of the Force. During her training, Windu allowed her to study Form VII variant known as Vaapad. She eventually became a Jedi Knight, renowned for her skills with a lightsaber and favored Form III when teaching other Jedi.
During the Battle of Umbara, the 212th Battalion and the 501st Legion were tricked into fighting each other by the fallen Jedi General Pong Krell. The 212th served in the Battle of Umbara along with the 501st, which was temporarily assigned to General Pong Krell when Skywalker was recalled to Coruscant.
The 7th Sky Corps was a corps of the Grand Army of the Republic under the joint command of Clone marshal commander Cody and High Jedi General Obi-Wan Kenobi.
According to wookieepedia a standard legion size during the republic era would be made up of 9,216 clone troopers. So we can safely say that the 501st legion had around 9,216 troops in their ranks.
Command. For most of the Clone Wars, the 501st Legion was led by Jedi General Anakin Skywalker, Jedi Commander Ahsoka Tano, and Clone Captain Rex, who served as their first in command.
The 212th Attack Battalion was a famed unit in the Grand Army of the Republic led by Commander Cody and Jedi Master Obi-Wan Kenobi. Part of the 7th Sky Corps of the Third Systems Army, it consisted of both standard infantry and clone paratroopers.
The 41st Elite Corps, later redesignated as the 41st Stormtrooper Legion, was a legion of elite clones in the Grand Army of the Republic, composed of many variants of troopers, including AT-RT drivers, clone scout troopers and BARC troopers.

By 21 BBY he developed a strong dislike for Mandalorians due to several of the mercenaries fighting for the Confederates, and he expressed this to the clone commandos of Omega Squad.
The 327th Star Corps was a military corps of the Grand Army of the Republic, composed of clone troopers bred to fight for the Galactic Republic. Led by Jedi General Aayla Secura and her trusted clone Commander, Bly, the 327th fought against the Separatist droid armies on multiple planets across the galaxy.
Shortly after the Jedi Purge and the formation of the Galactic Empire, the Grand Army of the Republic was absorbed into Stormtrooper Corps, given new armor and new weapons. After the Kamino uprising, the 501st became the last remnant of the Grand Army of the Republic fully composed of Jango Fett clones.
The 21st Nova Corps, also known as the Galactic Marines, was a prominent military unit of clone troopers noted for their unique armor and relentlessness in combat.
Neyo. The leader of the 91st Mobile Reconnaissance Corps, and Commander Ponds' replacement in canon, Commander Neyo has only a brief role in Revenge of the Sith.

Gregor, identified as CC-5576-39, was a clone commando who held the rank of captain in the Grand Army of the Republic. During the Clone Wars, he participated in the Battle of Sarrish. He commanded troopers within Foxtrot Group in the 212th Attack Battalion.
Look, he definitely isn't Mace Windu's son: the age doesn't match, considering the other character's ages (Luke, Leia, Vader, Solo, etc.). However, i think it's possible to see Finn as his grandson, but for that you must consider that Windu had a secret baby close to his time of death.
Legend had it that Yoda—a Jedi who became Grand Master—was trained by N'Kata Del Gormo. A Force-sensitive Hysalrian, N'Kata Del Gormo was trained in the ways of the Force and achieved the rank of Master within the Jedi Order.
Still, Finn's increasing Force-sensitivity proved essential during the Battle of Exegol, and he's also clearly cultivated a Force bond with Rey. All this appears to set Finn up as one of Rey's first Jedi Padawans, training under her in order to master the Force.
