My mother was a Moore. She was born in Carroll County Md . The family moved to Illinois and then to Virginia. My wife and I are tracing the Moores. It could also be a derivitive of Mohr , Moor , or any other spelling. Depends on what port of entry the family first came into, and whether or not the record keeper took the time to get the spelling correct. But, without some records of your forebears, Its hard to trace. Wear any kilt that suit your fancy. Its not the color, but the wearin'. Good luck in your search.

P.S. Could also be German. Now that throws a wrench in the works.
