Like FO4 for example.
Having around perhaps 100 names(50 male and 50 female ones for example) recorded or so in where at least our companions or some of them (or family it was mentioned) recognize our first name in here.

Edit: Also feel free to suggest which names would you like recorded if it were to happen. Personally I would like John and Jane as tribute to Shepard in here 
All we need is a middle name for the sake of recognizing save data. We don't need a list of names. It would sound weird if names are just inserted into the spoken dialog like that. You'd have a situation where everyone picked only the names that didn't make the dialog sound cut up. I didn't pick my name in real life. Most of us didn't. In my case my father did. Just make it Jake, Rosita or Demetri or whatever. Having a player created first name is so utterly useless if that name is never used. The player given name in ME was nothing but a save title.
To have Liara, your creepily obsessed stalker crush or Tali "I have Shepard porn installed in my suit" vas Normandy not even know your name and call you Shepard was annoying. Garrus was my brother... MY BROTHER!!! And he didn't know my first name. Da fuq?
And now we'll have a actual biological sibling(s)and parent(s)? Cousin(s)? I swear, if none of them know my god damned name...
