In the lower part of the info section about Volodymer Monomakh, it says that his great-great grandfather is Abu Taghlib (see Fadl Allah Abu Taghlib al-Ghadanfar ʿUddat al-Dawla, Emir of Mosul)
What's the source for this? I am very interested in learning more. If it's based reliable sources, then the connection from Abu Taghlib needs to be made back.
