Does anyone have any information on the two children Edna and Hazel Klindt in the Beals photos?

Margaret Klindt b. ?1844, d. 26 April 1893 in Jackson County, IA married first Gustave Jebsen 10 December 1867 in Jackson Co. Gustave died 3 May 1877, and Margaret married second Nicalay Matthias Jensen on 8 November 1859. Margaret may have been Nicolay's second wife of at least three. It is a complicated family and if anyone has more information on the Klindt-Jebsen-Jensen-Christiansen family, I would like to discuss it with you.
