This may not be pertinent to your search but involves Celanders in Iowa. The witnesses to my grand parents marriage in Waterloo, Iowa in 1910 were Reynold and Signa Celander (brother and sister). They were the children of John and Carolina Celander (maiden name may have been Johansson). They were married in Ottumwa, Iowa in 1887 and later relocated to Oakland California about 1913.
