My name is Michael E. von Kempf of Seattle, WA USA.
I've been trying to find information on my family (von Kempf) in Germany and Austria and it appears that no data reguarding VON KEMPF's have been converted to electronic database from paper docs as of yet but don't quote me on that, i'm still looking.
My grandmother, Margaret von Kempf travelled to Germany twice a year for a good many years to trace our ancestry first hand, you may need to do or have some one do it in person.
Feel free to email me if you have any curiosities.
Sincerely, Michael Eric von Kempfmrpink1969@hotmail.com
