I think the book just means that a bunch of the Septim Emperors were raised and/or ruled in High Rock before becoming Emperor, which some did. Wayrest was ruled by many different Septims, like Solitude was.

Anyway, I have never heard of a Redguard marrying into the Septim line. I have heard of Bretons, Imperials, Nords, Altmer and Dunmer.
