On my mother's side, my great-grandfather had a 500 head reindeer herd in Finland. Gave it up to move to US before Finn-Russian relations soured. In MN, he became the 'go-to' guy for well builders back around 1910-1920. His dowsing was very accurate according to the old records and writeups we found.
On my Dad's side, my great-grandfather was a Prussian general who left the Army when he was about 38. Married a woman here and she had 15 children (all lived to adulthood).
