No not anymore. Katherine Kohli is his great great grandmother. Katherine was married to David Karlen whose paternal grandmother is Anna Zabli (west African name). On David Karlen's maternal Kammacher line about four generations back is a Jaggi (VERY common Northern India name). I got all of this on
www.familysearch.org. This is the LDS site and free to all.
BTW I have been doing non-stop historical research and there was a lot of migration from India and other parts of the world to Europe. This does not appear to be as uncommon as one might think.
(Me on my soapbox) We need to get out of our "little box of Euro-centrisim" and into the "big tent of hummanity" where the big fun party is going on:)
Thanks for being open minded
