I apologise for that mistake, littlemissm.
Gemcgem, unfortunately by using a 'creative' spelling of a name rather than the correct one, you have somewhat called attention to your spelling. Someone who didn't know that Esmae was a deliberate choice, could see your other misspellings and assume that Esmae was another mistake on your part.
I am afraid I do tend to think that Esmae belongs with the Kaylee/Ashlei/Ezmi/Taylah names that have a reputation as being chavvy, and Esmae may well be tarred with the same brush.
Incidentally, I wouldn't trust the mumsnet namefinder 100% - not when it offers Shardonet (a misspelling of Chardonnay), and Chenel, Jaxon, Sharn, Zuzanna, Zsuzsanna, and Zanthe - all of which look like misspellings to me too (Chanel, Jackson, Sian, Susannah or Susanna twice, and Xanthe).
