Yago is the house/clan name of a family and is composed of a root name and prefixes/suffixes. Thus people having yagos with the same
root name are directly related. As the family grew and separated, prefixes and suffixes were added to the root name to describe primarily
the relative location of the new house. This data set contains Yagos of families from Nakagusuku-son Aza-Arakaki.
