Talk:List of state leaders in the 11th century

Orphaned references in List of state leaders in the 11th century
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of List of state leaders in the 11th century's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "FactsonFile": From Count of Poitiers: Monarchs, Rulers, Dynasties And Kingdoms Of The World, by R F Tapsell, 1983, Facts On File, Inc., New York, NY, page 211. From List of state leaders in the 9th century: Monarchs, Counts, Dynasties And Kingdoms Of The World, by R F Tapsell, 1983, Facts On File, Inc., New York, NY, page 211. 

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 20:42, 29 October 2020 (UTC)
