Please consider looking at “A Modern Guide To Demons And Fallen Angels” by Paradox Brown: http://paradoxbrown.com/
I have referenced some of the chapters below.
The first wave of fallen angels (taken from:) http://paradoxbrown.com/genesis6sonsofgodfallenangels.htm/
“For if God spared not the angels that sinned, but cast [them] down to hell, and delivered [them] into chains of darkness, to be reserved unto judgment; And spared not the old world, but saved Noah the eighth [person], a preacher of righteousness, bringing in the flood upon the world of the ungodly; And turning the cities of Sodom and Gomorrha into ashes condemned [them] with an overthrow, making [them] an ensample unto those that after should live ungodly” 2 Pet 2:4-6
“And angels who did not keep their own domain, but abandoned their proper abode, He has kept in eternal bonds under darkness for the judgment of the great day. Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.” Jude 1:6-7
