Newer research in the German and Czech literature seems to suggest that both Emmas are the same. (See bio for Emma z Čechy http://www.wikitree.com/wiki/Unknown-322801)
Considering the circumstantial nature of the argument is the evidence strong enough to merge those profiles or should they stay separate with an explanation of the research in both bios?

Just a note: it's John Atkinson and EuroAristo ('o' not 'a' at end).
