I am a little biased, because I had a terrible experience with a [name_f]Tatiana[/name_f], but I have another point in favour of [name_f]Talia[/name_f].
Talia’s meaning, “dew from heaven; by the water”, is so beautiful. It makes me think of peacefully floating down a river or sitting at the edge of the sea.
Tatiana’s meaning is unknown; it’s a Russian name from an established [name_m]Roman[/name_m] surname. It definitely has a strong history and a beautiful sound and has been used in literature, but the lack of a particular meaning, especially when Talia’s is so beautiful, sways me in favour of [name_f]Talia[/name_f].
