russian name

No it's their first name.
Almost all Russian and Slavic girl/women first name will end with an " a ".

In many online dating sites , most of the time , only the first name of the women are public.

It is when you have established a really good relation/communication with such a lady , that she may tell you her family name.

And other personal info.

thank you for information

Hello.
Russian girls don`t have 2 names like in the USA, where there are: Anna Maria (1 girl).
In Russia people have 1 surname+1name[Anna (1 girl), Maria (another girl). Or Yulia (1 girl), Elena (another girl)] +1 patronymic.
