93 AllMyWill,
I wouldn't pay much attention to the whole Frater/Sorror thing in my opinion even though that is tagged along to the name you choose , it is not a part of the name. The equivalent of joining a fraternity/sorority and refering to you fellow members as brothers and sister , frater=brother , sorror=sister.
I felt the need in the beginning of my path to choose a magical motto early on to seperate my new magickal life from the old mundane life I was trying to escape from. I will explain how I chose my name and if you like the method give it a try.
After a bunch of google searches on "how to choose a magickal name" and things of that nature I decided to chose a name using numerology. I used a simple method I found on some site related to magick. You take the digits of your birth date and add them up individually. When you get your answer continue adding those digits until you have a single digit number. The only double digit numbers the page said were acceptable were 11 and 22. Once you have added it all up and you have your number that is your life path number. Now find names that you like and add them up using the chart below to find the value of that name. I feel this method starting off is a good way to choose a name with a little more meaning and more personal. I will give an example below.

My birth date is 07/02/1991
7+2+1+9+9+1= 29
2+9=11
Out of curiosity I also added my first and last name up seperately and they also both added up to 11. I then hit google again to try to find a word or phrase in another language, god name, etc that resonated with me. One of Crowley's many names was 'Perdurabo' (Latin: "I Will endure to the end").
I chose Isa(ee-sah) which is short for Isadoros or Isadore and means "gift from Isis" which I have my own personal reasons as to why that resonates with me that I will not share. I felt that Frater Isa was missing something it did not sound complete. I just kept adding up random things that I liked and landed on gold. It was a 2 which is my 11 broken down 1+1=2. Which is also my birthday July 2 so it worked. I googled up metaphysical properties of gold and things related to the color I liked it and it stuck. Once I get a grasp of gematria I will probably look into a name with more meaning and significance to me, hopefully when I'm ready to make that step into initiation as a neophyte in my local OTO.
Any how I am glad I read this post for a while now I have wanted to start my own thread sharing how I landed upon my name and to ask others if they would like to share what their name means or method use to acquire it, etc. I thought some may feel it too personal to explain something that may be extremely personal to them however if anyone would like to share I'd love to read.
Love is the Law, Lover Under Will.
