RegEx Expression help please

[Amsaini15]

Hi

 Can someone please help with writing RegEx expression to filter out all special characters, brackets, numbers. I am cleaning a first name column which can only have alphabets, - (hyphen) and ' (apostrophe). 

Also it should flag single alphabet field as False. Thank you

REGEX True/False output should be like this

Alex!   - False

Jam@es - False

Li%sa - False

(John - False

[Raj - False

Tony\ - False

George~ - False

Jamy* - False

Rob^ - False

Mary-Anne - True

O'Connor - True

Jacky12 - False

Rob0rt - False

n - False

L - False

warren - True
