Re: i can't find the meaning of my name
well, what i've found is:
Seleke, a Dutch female name, derived from either Marcelis or Sale; Sale probably means 'dark coloured' and Marcelis, see Marcel (follow the hyperlink).
Seleka, a surname used in South-Africa and Botswana, meaning unknown.
When searching on Seleca, i found a bookstory about Seleca being the nymph that united with Hermaphroditus in Greek mythology, but this seems a mistake by the writer, because all other sources say the name of the nymph is Salmacis (or Salmakis).
Your name is indeed very difficult.
