hi. not too sure about Ludwig Odewahn but i do know a Carl Richard Odewahn. Not sure when he was born but was married in 1912. There has been research done before and i do remember hearing that there was a book but i think this more follows the lineage of the LINDNER family to whom Carl Richard married. here is a link to a site which has that family tree http://familytree.castinet.com.au/2/637.htmhttp://familytree.castinet.com.au/2/637.htm.
would be interested to seethe relationship between Ludwig (ie. brother, cousin etc). I have tried searching many countries phone directories to see if there are any other Odewahns however I only seem to be able to find them here in Australia and in US. Not sure if any of this helps, but anyway,I guess I am a descendant of Ludwig in some way . Regards Kyle
