Recently I saw Ancestry notes lifespans of people w certain surnames.

3. You can try 23me.

I do quite a bit of genealogy and DNA work for people as a hobby and all kinds of things turn up like this.

I like the Ancestry DNA testing because they have the largest data base and also your matches have more family trees which gives you information about your background.

That said, 23me gives a bit more accurate results.

If DNA testing from another site also shows no German DNA, there are a number of reasons why this could happen.

Country boundaries changed a lot over the years in Central Europe, so you can look for DNA from adjacent areas. Look to see if the report is showing slavic DNA.

Sometimes our ancestors changed names, nationalities, etc. for some reason.

Or there could have been an unknown adoption somewhere along the way.

Look at the rest of the DNA report and also look at the ancestry match list. Look for Gerhart surname matches. Look to see their DNA mix.
