Morana

If anyone is named Morana then I'm sorry, but it isn't a good name. I mean, the name itself is beautiful but the meaning behind it, not so much. If you go to any Slavic country and tell people you're named Morana they will look at you in shock and take two steps back. Since Morana was literally the goddess of death, there is still a lot of resentment towards it.
For example in The Czech Republic (where I'm from), the ritual drowning of Morana still takes place. Every year people make a child-sized doll out of sticks and straw, paint her with coal and dress her up in black rags, animal bones, dead flowers, and throw her into the river. This signifies the end of winter, hunger and death. And even after millennia of Christianization, this ritual has stuck around.
Naming your child Morana is tempting your fate even more than having a May wedding.
Then again, if you go for that kind of stuff, to each their own I guess.

The name doesn't mean death in any Slavic language... it is however in relationship with the proto Indo-European word mar, mor, which means death. It is also connected to mor-the Latin for death and Russian for pestilence. One of the Roman god of war Mars' names was Marmor. Nightmare is also a word that has some connection with this deity (Croatian-noćne more).

Morana, Slavic mythology, was goddess of nature and death. But without her husband, Morana turns into a frustrated old hag, a terrible and dangerous goddess of death, frost and upcoming winter, and eventually dies by the end of the year. At the beginning of the next year, both she and Jarilo are born again, and the entire myth starts anew.

Morana or Morena was the goddess of death and great peril in Slavic mythology.
