The profiles represent the same person, but there is a big problem with Unknown-8182, the "daughter" attached to Dagobert II "Unknown". Her "line" continues for several generations without the least source in sight. Worse still, her biography makes her the daughter of "Mathilde de Razès". Merovingian-85's biography on the other hand, states that Dagobert II was never married to "Gisela" de Razès (different name, same story).
The daughter must be taken care of and disconnected before the profiles are merged.
