A proposal has been made for a multilingual Wikipedia. To make it work it will use available information in Wikidata.
Above you find genealogical information of Nintoku, a Japanese emperor. As you can read in the screen shot 1990 people are included and you may notice many of these people do not have a label in English.
As there are labels in at least one language, it is possible to transliterate it into other scripts and or other languages. There are standards for transliterations and consequently it is technically possible to create the missing labels.
