User blog comment:Essie Essex/Ella or Emma?/@comment-16533050-20131014091809

Okay, so just replayed this mission for the sole purpose of getting this lady's name. Here's the deal:

When she's talking about the Brimsleys, the male aristocrat originally standing next to her calls her Emma. After the conversation between her, the first male aristocrat, and the second male aristocrat that joins the conversation later, the three split up.

If you talk to her directly at this time, she says her name is Ella. Then a second interaction with her lets you know that there's a large vault of treasure in the basement.

Since there is an 'Ella' signed in the book, I'd say that's her name. The 'Emma' was probably a mistake on the devs/writers part, but if you make a page for her, I'd say go ahead and add in the 'Trivia' section that a male guest mistakenly refers to her as 'Emma' by most likely a writing oversight.

Hope that helped.
