First of all, I looked up the name Avara and it is not Finnish, but Sanskrit meaning "the youngest"(and it is definitely a girl's name). Pretty cool, it should be added here along with these other Finnish names I remembered...
Aarne (M)- Finnish form of ArnoldHeikki
(M)- Finnish form of Henry
( if this is already here then exclude it).
Elviira (F)- Finnish form of ElviraInka
(F)- i know thia name has an entry here but it is also a short of form of the Finnish name Inkeri
so it is essentially a Finnish form of Inga
Miia (F)- Finnish form of Mia
Aliisa (F)- Finnish form of Alice
Eliina (F)- Finnish form of Helen
along with te name Helena
Hopefulyy I'll be able to add even more...:)
