Most Project Administrators have probably had a discussion with someone who insisted that a person matching them couldn't possibly be related because they spelled their name differntly - often with a very minor difference - such as with (or without) an "e" or an "s".
We support a project that is really fun to look at for the name evolutions as immigrants came to America - the Palatine project at http://www.worldfamilies.net/surnames/palatine/results
Here are the names from the Lineages (men who share a recent common ancestor):
Hamm & Ham
Gnaegi & Kornegay
Loucks, Laucks & Laux
Herder, Harter & Haurter
Meisser & Meiser
Bauch & Bouck
Presley & Preslar
Add the ones that you've chuckled about as a comment if you wish. (Note - I now have to approve all comments as the spammers were having a field day with our blog.
Have a great day!
