Goran Jovic in Are Jews in Chapterhouse: Dune the same cultural group as in our universe/timeline? states:
... a book which features direct descendants of Ancient Greeks in far future as main characters.
Is that really the case?
I thought that the Agamemnon was merely the alias that the Titan Formerly Known as Andrew Skouros took because he admired the historical figure.
Wikia seems to disagree, but provides no actual evidence:
Skouros in some way could trace his lineage back past the Time of the Old Empire, thousands of years to the House of Atreus and a famous ancient King Agamemmon.
Is there some specific in-universe evidence to back up this biological link?
