I am the daughter-in-law of Gertrude Kneip Cirks who is the daughter of John P. Kneip and Margaretta Beitz. Margaretta is the daughter of Adam Beitz and Julia Burg.
Gertrude is now about 93 years and when we were visiting her in Ada, MN last February, she said Aunt Carrie married Wolfgang Schreiner and they lived in ND. Is this "Carrie" the same person as your "Caroline"?
Gertrude said there were John, Joe and Mary, Peter, Henry, Julia, Jake, Kate, Margaretta in the family of Adam and Julia (Burg) Beitz.
