From Gineipaedia, the Legend of Galactic Heroes wiki
This should actually be Goldenlöwe Dynasty. If you look at the furigana at the end of episode 109 — see right — it says 'ゴールデン・ルーヴェ' gooluden luuve. Luuve is Japanese bros' way of saying löwe, and does not correspond with the Japanese spelling/pronunciation of Reinhard's surname.
(... Which is actually inspired by the name Lohengrin. You can see that the Japanese Wikipedia article on this subject uses a spelling that matches Reinhard's name — 'ローエン' looen. So these are clearly different words.)
Note: I have not actually changed the title of episode 109 yet. ♥ kine
