That was the topic answered by the authors featured in the 27th edition of the Carnival of Genealogy, posted July 3 at Kinexxions. Sorry to be so late in getting the announcement up!
There's still a little time to get submissions in to the next Carnival. The due date for the next edition is July 15th:
The topic for the next Carnival of Genealogy will be: Surnames! Pick a surname on your tree and tell us about it. What are it's ethnic origins? Has it morphed over time as your family has used it? (or at Ellis Island ;-) What does it mean? Is it common or rare? What are the common misspellings? Any famous people or places with your surname?
I've submitted two articles to this one, my visits to two places named Geyer in April and May, and my write up on German surname information at Ancestry.de. Both are a couple months old, but I thought they fit the topic perfectly.
