 Where Hawaiian ancestry was involved, including the cultural tradition of informal adoption known as hānai, some of the spouses were known by more than one name in addition to their married names.The practice itself, sometimes described as the Hawaiian foster care system, blurs the accuracy of how many children in a family are the issue of either parent, or fostered into the family.For that reason, obituaries often varied from source to source in reporting the number of children of the deceased.
