Long before the Masonic brotherhood had called each other by the name Bro.', they would greet one another by the Old English name of "Feolagan Wed Brodra" A name meaning pledge brothers and or Brother of Odin.
The predominant language up until about the 13th century was Old English; and it eventually evolved into the modern English that we speak today.
The various Old English words that I have found related to the modern Bro.' through my research, are as follows; "wurdon feolagan or fiolagan, wed brodra, wed Broders meaning fellows, sworn brothers, pledge-brothers or Brother of Woden."
Today of course they would simply call one another Brother or Bro.'
Below are some examples of these historical Feolagan Wed Brodra events I have discovered that are mainly from around the 6th-11th centuries .
* Aethelbald and Offa: two eighth-century kings of Mercia made 7 wurdon feolagan 7 wedbrodra’ (‘the two kings came together at Ola’s Island near Deerhurst. and they became partners and pledged brothers’)
* King Oswy, in 656 is spoken of as a web broder of Mercian King Wulfhere
* Anglo Saxon Chronicle of the Traey between Knutr and Edmunds become Feolagan Wed Brodra (feolagan and pledge brothers)
* Hengist (Of Hengist and Horsa) calls Ebissa the Wed Broder of his son Oeta
* In the shipmans Tales where he says of the merchant of st dennis and the monk, the broper hedge of Arthur’s court to which is made sir gawayne and the green night
* In Shakespeare: Richard II, the king says, I am sworn brother, sweet, to grim necessity and he and i will keep a league till death
* Anglo-Saxon Chronicles 1016- reports that kings Eadmund and Cnut met near Deerhurst and wurdon fiolagan and wedbrodra “became felagar and sworn brothers”
