I was contacted by a Greg Pracht whose family was from Florence, KY near Cincinnati, OH. He said in contacts with some busines partners in Germany he was informed that our name originates from near Hamburg and roughly translates to crown jewel.
My Pracht ancestors settled around St. Louis, MO. My maternal great-grandfather Zachaus Pracht was born Abt 1891 in Lenterschack, Near Marktoberdorf, Bavaria, Germany. I hope this helps.
