#Wikidata, you will find a succession of the sultans of Sennar. The information provided is limited because the articles about them are limited. There is no date of birth or death information and for only a few it is known who the fathers, the suns are.
On the Arabic Wikipedia, the article about Sennar has red-links for the Sultans. When you include them on the articles at Wikidata, do they become "infra red"-links?
Sennar is an important part of the history of Sudan, and consequently it is relevant to have information in Arabic. Copying in the red links as labels seems obvious. The question is how to make it more obvious for the Arabic Wikipedians that Wikidata has information relevant to them.
