plus, of course, the wonderful http://www.recons.org/

50 LY is near-enough 15~~16 Parsecs, so you can use search parameters of main-sequence G-type (to exclude 'red giants') plus 14~~17 parsecs / 45~~55 LY, and sky position as orthogonals set by RA & Dec...

I suggest you look at nearby stars first to work out a search strategy. At least all the G-types will be included at 50 LY: A lot of red-dwarfs and most brown dwarfs are 'missing' by that distance...

You must allow some wriggle-room as stars move, Earth's pole precesses etc etc.
Google and Wikipaedia are your friends...
