From so many sources it's hard to just nail down a few, but I have a personal library consisting of many books on Church History specifically between 100AD and 400AD. I also have read a large amount of 16th through 18th century English books detailing much similar info ...not many people know this, but in England's colonial days they also did a huge amount of manuscript collecting, much around Arabia, North Africa, and also did much work with other European nation's in manuscript hunting. What this produced is a large amount of publications that you can find printed out in 16th/18th century English books, many of which you can find for free online on Google, or the Internet Archive.
But also following various books on Roman Emperors starting with Julius Ceasar and onward, and following the characters within the details will also rabbit trail you to mix in other info sources.
However you can find much of this info if you review all the "Council's" concerning the "Arain Controversy" there are 25 of them, also reading the Creeds of Arius, or of the "Arian Orthodoxy" post Theodosius I, for several of Constantines heirs were anti-Trinitarian, but also much of these details are listed in Eusebius of Caesarea Church History ...it don't take much research to find that he and his fellow brethren were exiled by Constantine, but also reading books about the Palestinian martyrs, and the books of the Syrian Church will render much additional info.
...I'm not the only one to come to such conclusions, but also many OLD-SCHOOL Unitarian's (not modern) have come to the same conclusions. It is a bit of a chaotic mess of info, but there is some order, you just have to understand many of these books about Arius were burned, and many zealous Romanist altered much, and slaughtered many. Not many people know, But Rome's Barbarian overthrow was Arian believers who before that time were seen as Roman, but ransacked Rome destroying many of it's pagan idol's. For this Charlemagne made sure to wipe them completely out of existence for this at a later date when Roman Empire became The Holy Roman Empire and was once again stabilized under monarchies, and it's state church.
