Bulgarian / English boy names

[FHmama]

Does anyone have any suggestions for Bulgarian boy names that are also easy to pronounce in England and are tied to an English version of the name

Think Aleksander ie Alexander, Viktor ie Victor etc

Any suggestions are welcome, thanks

Ivan is related to John. Although English people would probably pronounce it Eye-van rather the EE-van.
Valentin/Valentine?
Toma/Thomas?
Marko/Mark?
I think Alexander is a good choice with lots of shortened options, although it is popular.

Adam
Anton - would typically be Antony/Anthony in English, but Anton is used/familiar
Daniel
David
Emil
Ivo - I think this would traditionally be short for Ivan in Bulgarian, but is a stand-alone name in many European languages and used that way in the UK
Kristian - more commonly Christian in English, but Kristian is also used
Martin
Milan - not traditionally English, but popular enough from other European languages plus the city of Milan that it could work well
