Demi Lovato is supposed to be my 8th cousin, twice removed, with the MRCA being Maria Margaretha Schopferin (1662-1750), the great grandmother of Magdelena Dockstader, the furthest back in that particular lineage I have documented.   4th great grandmother Dockstader was born in a province of what is now Germany — I have not been able to pin it down.   So,that would mean at least 4 generations of German research to include this line.  Then there is Demi’s lineage: 4 generations of Smith, 2 of Hopper, and then variations of different spellings of sound alike names.  This could turn out to be a very LARGE PROJECT!
