Pretty good synopses.Unfortunately, during the battle of the Pacific in WW2, most of any written records were lost during the bombing of Okinawa. Much of what we know is based on oral history passed on in regards to the earliest years.
There were 36 clans/families sent from China to Okinawa to help starting in 1392. The number "36" is symbolic and it is really unknown if that number was picked due to it symbolism and there were more/less sent, or if that number was specifically sent due to it significance. Either way, it is one of the earliest documented places where China and Okinawa had open relationships. From there, you get into oral tradition, that can't be confirmed about certain okinawan katas. Wansu, Chinto and Kusanku are all thought to be either created by, or created from teachings from Chinese kung fu practitioners that were on Okinawa.
There were 3 main cities in Okinawa that gave birth to "karate" Shuri, Naha and Tomari. They were known by the city and "te" meaning "hand". So, Shuri-te later became styles like Shorin-Ryu and Naha-te later became styles like Goju-Ryu. Tomari-te no longer exists as an independent style and is believed to have been incorporated into the Shuri based styles.
Naha-Te styles originate mainly from Kanryo Higoanna who went to China himself and studied a type of karate/kung fu while there. There are many theories on what he learned and who his teacher was. Kanryo had two main offshoots from his karate. To'on-Ryu and Goju-Ryu, both have the main four katas (seisan, sanchin, sanseiru and suparenpei) but differ on the other katas. One theory is that Chojun Miyagi did not learn all of Goju-Ryu's katas from Kanryo but created the others himself based on what he had learned, the other theory being that Kanryu taught him the "secret katas" that he shared with no one else. The other main style of Naha-Te is Uechi-Ryu. Kanbun Uechi also went to southern China and learned kung fu and brought it back to Okinawa. It was taught exactly how he learned it in China without changes when he taught in Okinawa. Uechi had seisan, sanchin and sanseiru but not suparenpei, there is dispute among people if he didn't learn the 4th kata or if what he studied did not include it. Kanei Uechi, changed what his father taught as karate spread and modified it to a more japanese approach and it was during this time the other kata were created.
Shuri-Te styles go back further and seem to be based on chinese kung fu that was brought to Okinawa and was combined with their own indigenous art(s). The main Shuri style today is Shorin-Ryu (Funakoshi was a student of this lineage in his creation of Shotokan). Sakugawa is the main person who was responsible for the "importing" of karate to Shuri. His student was Matsumura and then Itosu. Itosu was one of the first who wanted karate to be widespread and taught to everyone. He went on record stating that he altered the katas to make them safe for school children. Itosu also created the Pinan forms based on older kata. Itosu penned the "10 Precepts" and states that karate did not come from Confucianism or Buddhism.
There are other karate masters who were very important in its development, but this is kind of a quick overview.
The only hick up is that to my knowledge Kanbun Uechi didn't bring his art to Okinawa, he taught in china and on the main land Japan. It was his son and his student who returned to Okinawa. Kanbun from what I understand taught Chinese kung fu, using the Chinese language and the full curriculum including herbs and medicines.
