Whats my name?

So I'm starting to get to the point where I need to start officially changing all my official documentation to reflect a new female name. I want this to be mostly in place around when I start going female 24/7 which I'm still shooting for summer on, though probably closer to late summer. Usually big decisions like this I let permeate in my subcontious till something triggers and answer. I'm almost there, but due to my timeline, I have to start thinking it more actively. Luckily, I'm down to a few names I like on the first name unless something completely unexpected come up that sounds great. The last name, I'm not so lucky on. To be honest, I totally forgot about picking a new last name till only recently so I haven't really thought about it as much as I should of. I know some may way no reason not to keep my current last name, but I feel strongly that as part of a full restart, I really do need a new one. So that will probably take a little more thought...
