Hello, I was browsing for my name and saw that information about my name is incorrect.
First of all
ELINA in Latvian is
Elīna. Relative name is
Helēna. Your mentioned names
Jelena and
Jeļena is not latvian names, those names are russian names and comes to Latvia in soviet union with russians and contemporaneity are used only in russian migrant families. If you know that latvian language is far from russian so there are no common usage.
