How would I spell these names in Russian?

Hailey = Хейли, Хэйли, Хайли

Gretchen = Гретчен, Грэтчен, Грэтчэн

Хэйли(or Хейли) , Гретхен....In Russian literature and translated movies u can here these names ...Pronounced the same way as in English(Hailey) and in German(Gretchen)....

I guess u have some problems with correct pronunciation of the name "Gretchen" - the combination of letters "tch" sounds like "t+h "or even "t+kh"(k should be very soft) and in Russian it will be correct to pronounce this name in 2 ways :the first "e" can sound like "e" or "a" - both will be correct.

Well, I should add...If your Gretchen is from Bavaria, her name will be pronounced kinda another way "Gretshen"(sounds "sh" instead of "kh") but spelling is the same. In this case her name will sound in Russian the same( "sh").But it's very rare.

Hailey is Хейли or Хэйли allright, but for Gretchen I would suggest Гретхен (if you pronounce it like Gret-hen).

ГРЕТЧИН = Gretchen and I have no idea how hailey would be spelled, sorry.

maybe Hailey could be ХЕИЛИ

гретчен=Gretchen

Хейли=Hailey

Гретчен would be Gretchen

Hailey could be transliterated several ways - I think Хейли is the most accurate
