Levenloos literally means “lifeless” and is used to refer to stillborn children. In death records, you will often read “levenloze dochter” [stillborn daughter], “levenloze zoon” [stillborn son] or “levenloos kind” [stillborn child].
Since 1811, death records were created for stillborn children (children born after a pregnancy of more than six months). They did not have birth records, as these were reserved for children that were born alive. If a child died before the birth record was created, a birth record was still created, as well as a death record. Before 1811, it is rare to find records for stillborn children.
