Jacob Pflaum's name was really Johann Friederich Pflaum. He anglicized it when he and his wife Carolina emigrated from Bade,Germany to Arago,Richardson Co, Nebraska(now known as Rulo and Falls City)
He had 7 children: Emile,Karl August,Freda Catherine, Frank,Friederick William,Anne, and Katherine Pflaum.
I am the granddaughter of Freda (Pflaum)Breckenridge. I have some information on the family if anyone is interested.
