I don't have one I named after myself, but I do have a dwarf that I share a fairly large amount of empathy with...
When I was starting my fort, at embark, I was looking through my dwarves' personalities, and found a good candidate for a leader - she was never discouraged, made friends quickly, easily moved to pity, often cheerful... but she also had "dislikes intellectual discussion". As such, I named her "Sunny", and gave her a few ranks in pacifier and consoler. (Primary profession as carpenter, secondary as brewer, although she dropped that when I got migrants.)
To compensate for a lack of thinking, however, I got another dwarf, one who had "takes time in making decisions," "open-minded to new ideas," and "Candid and sincere in dealings with others" as traits, and gave her my appraisal ranks. (Primary profession cook, also odd-jobs until migrants.)
I kind of like the notion of having a leadership duo with a charismatic "face" who manages to motivate and negotiate, and then a dour manager who does the actual planning and work. Since she was taking this psuedo-support role, I named the second dwarf "Luna" for completeness.
It kind of helps that Luna is not just record keeping and trading and price setting, and was my first legendary, but is also pretty much running the show in terms of fortress value, as her legendary cooking skill makes her capable of pretty much sneezing on a quarry bush and making it worth more than most artifacts. (I just keep notions that she's "staying in the kitchen" aside...)
I prefer to picture her as doing the actual planning of fortress design, while Sunny runs around hugging cats or demanding more goblets and fine pewter or meeting with dwarves who are unhappy that they are bankrupted by housing prices caused by all my beds being high-quality.
Oddly, when enough unhappy dwarves got together, even though Sunny had successfully dealt with all the complaints, and even did a "carpenter's union" mandate, they actually did elect a new mayor... Luna! Now Luna's finally being seen for all her hard work, even if she may not exactly enjoy the additional responsibilities... (I was just working on giving Luna nicer quarters, as well, but now Sunny and Luna are switching rooms, since my mayor's housing is pretty nice.)
edit: Oh, Luna's last name is "Thathilstukos", or "Autumnrazor". Sunny's, if anyone cares, is Kubukribar = Lancehomage.
