“ Joseph Gauss, son of C. F. Gauss' first marriage, who remained in Germany, later had a son, his only child, named Carl, who is still living (1926) in Hameln, Germany.
Ewald, mentioned above, was the German Orientalist, who first married Minna, C. F. Gauss' daughter by his first marriage. Minna is said to have had a good deal of her father's mentality, but died a few years after her marriage to Ewald. Ewald married again, as stated in above letter.
C. F. Gauss' second wife was also named Minna, and her daughter was named Theresa. Her sons were Eugene and William, who both came to America. ”

“ That your business is prospering gives me pleasure, but in a letter which your grandmother received lately there is a somewhat unintelligible intimation that you intend to give it up, to go into the country and there to carry on a wholesale business. ”
