Carl Marinus Christensen
Carl's father (Christopher) died in 1858 in Iowa. There is documentation that Mads traveled with his siblings (Gertrude, Carl Marinus, and Soren Peter) to Utah. However, his mother (Mariane Madsen Christensen) is not listed in company sources. Therefore, at this time it is not clear when she (Mariane) came to Utah.
More research is needed to confirm Carl's date of birth as sources give conflicting information. At this time, birth date listed reflects family tradition from Family Tree at FamilySearch.org and data from the the collection "Denmark, Baptisms, 1618-1923," at FamilySearch.org. Death date listed reflects data from an Ancestry.com Public Member Tree.
