My eldest hates her name, help me get it right for next DC!

[londoner01]

As we discussed the name for my bump my eldest DD, she is 11, said she hates her name, my 4 year old is yet to express an opinion...and so as my third DC is born I want to ensure i get it right!! I grew up hating my name until I 'grew into it', i want it to be a name my child will like throughout their life.. I like names which aren't common (as DD hates being one of many of Amys) but arent too out there or eccentric!
So far I have... Amy and Kyra...
I like...
Lotty/ie
Tegan
Mia
Thea
Lydia
Olivia (bit common though)
Evie
Saffy
Callie
Tilly
Megan

Opinions!

Ds has a "full name" on his birth certificate, and has always been known by friends/family/school but the short version, so can't see that (eg) Robert/Charlotte on the birth certificate would be a problem

Lotty/ie..dislike
Tegan..dislike, abit harsh
Mia...love it but very popular recently
Thea...like
Lydia..dislike, makes me think Clamidiya
Olivia ..dislike
Evie...like but too popular, what about Eva?
Saffy..dislike
Callie...OK prefer Cassie/Cassidy
Tilly...dislike, reminds me of that awful Tilly Vosberg
Megan...like alot but very popular also

Thanks for the replies- We are down to Thea or Lotty for a girl. Also liking Flo but unsure about Florence or Flora. And for a boy, Max, Leo or Harry. DH loves William but its soo popular, think he is sold on Max, or Harry- hes not so sure about Leo!
Find out what sex it is next week so we shall see! Hoping for a boy (DH desperate for a boy!) although I can't imagine it being anything but a girl after having 2DDs! But 3 DDs would be lovely!

Ooo I suggested Max or Leo! Can I take credit?
