Can I call my daughter Eleni...

[Elbugly]

... when my name is Eleanor?
I know I can but should I?
My OH is Greek so we've been looking at Greek names too and we are in love with Eleni but having second thoughts because of the similarities to my own name.
We already have a Theo.
Btw I go by Eleanor not Nella or Ellie or Elle.
Surname begins with D.

Other possibilities:
Thalia
Lucy
Athena
Tia
Ophelia

How is Eleni pronounced? Is it like said above - like elaine but with an ee sound on the end? Never heard it before.

Anyway- I don't think it sounds like your name if you go by no nicknames. Neither do I think it's 'vain'. I like a girl's name similar to my other halves name (don't like his mind 😂) and I wouldn't not use it for that reason. Why does it matter? I just like the name.

I admit the same initial thing could get annoying though with post. But then how much post will we even get in 10 years time? Get hardly any now, its all online!

Yes, it’s a different emphasis to Eleanor so sounds quite different

Thalia - is is Tahl-ya? Thahl-ya? Thale-ya? no
Lucy - love it
Athena - very nice but you'll need a short version
Tia - Aunt? Thanks in advance. No. Sounds like tear
Ophelia - no. I know one adult one but UK pronunciation (Oh feel ya) is too dodgy.
