Another necro. I was digging around the Brays as well. I don't believe it ever states Ana and Elsie are sisters (this isn't Frozen...:). They could be or might be ancestors of each other. The Bray Family is littered through grimoire as a family of significance. There are at least 6 Bray family members in grimoire, starting with: Clovis Bray: Founder of the Clovis Bray science facility on Mars. Appears to have ties to the technology behind the Exos and the Warminds along with the Ishtar Collective. He lived during the golden age. Clovis Bray II: Son of Clovis Bray (Clovis Bray Grimoire under Mars) Alton Bray: unknown relation or time (Meridian Bay grimoire under Mars) Willa Bray: unknown relation, golden age. She (sounds like a she) invented engram encryption techniques Elsie Bray: builder of eon trespass. Unknown relation or time Ana Bray: Guardian, post collapse city age, was at the Battle of Twilight Gap. There are also some ties to Cayde-6 in his journal I'd have to go look at. He was working for Clovis Bray as some sort of mercenary before he became an exo, owed them some money. Cayde gets a note from Clovis saying that Clovis is looking for someone like him, can forgive his debt. Soon after Cayde became an Exo Overall, interesting family that seems to be involved in some major historical events
