Simon Hathaway's grandmother

I wanted to ask you something. Which is... what's your name?
This article title is conjecture. Although the article subject is canon, no official name for it has been given.

The grandmother of Simon Hathaway was a Templar who worked quietly in the background of Winston Churchill's war office. Later in life she bore a child who in turn also married and bore a son, Simon. Her child, their spouse and her grandson would all go on to also become Templars.^[1]
