Lori..
I'm not related but I use to date a boy in high school who's mothers maiden name was Sourbeer. There are many Sourbeers in Clearwater, Tampa and Largo, Florida.
There are several who are practicing doctors too. I don't see them anymore but you might want to check the local phone directory for Sourbeers in this area or email me directly and I can give you a married name for one.

I'm not postively..but I thought some of them came from Ohio, Virginia or the Carolina's.

Hope this helps.
