I like
Leah Anastasia. To me, the
Anastasia spelling looks more traditional. And I think
Leah Anastasia flows well. I don't pronounce the "ah" of
Leah and the first "A" of
Anastasia the same, so I don't think they run together. Even if it did, you would not be calling her "
Leah Anastasia" the whole time.
"You sought a flower and found a fruit. You sought a spring and found a sea. You sought a woman and found a soul. You are disappointed."
"It does not become me to make myself smaller than I am." (
Edith Södergran 1891-1923)
