However there is a guy who lives in the same city as me and has the same first, middle, and last name who committed manslaughter that I was frequently confused with by the local press while his two trials (the first ended in mistrial) were going on.
Jeez, that sounds awful! I hope it didn't cause you too much strife.
I once lived in a town in Indiana where there were two families with my surname: mine, and this other family that wasn't really related to us in any appreciable way. This other family was widely regarded as a bunch of ne'er-do-wells, always in trouble with the law, involved with drugs and theft and other nonsense. There were occasions when people would judge me by my last name, including one instance where a Realtor discouraged a couple from selling a house to me. My Realtor found out it was because this woman thought I was from "that" family. She ended up losing her license over that.

It's kind of nice living in New Jersey where nobody gives a shit what your last name is.
