I am a woman named Adair, and my parents did a great deal of research on it before deciding, so I will share that information here. Adair (pronounced uh-DARE, per Gaelic pronunciation) is a celtic name believed to be of Teutonic origin and appearing most frequently in Scots Gaelic. It has no direct translation, but refers to oak trees or a place where oak trees grow. It is not actually related very closely to the name Edgar aside from a similar sound as the two names have a very different etymology. Also, to end the debate, it is GENDER NEUTRAL. In celtic naming tradition, there are essentially two pronunciations/spellings of each name, a "feminine" version and a "masculine" version. However some names (like Adair, Bret, Sloane, Blair, Morgan, etc) have only one form of spelling and were used for children of any gender.
I have only ever heard of the name being a female one. It is my middle daughter's middle name as it is/was her grandmother's, great-grandmother's, and great-great-grandmother's middle name. I think it would be lovely for either though.

It doesn’t have to be a male or female name. It can be both or for neither. Adair fits me perfectly as a nonbinary (trans) individual. It also gives me a sense of peace and belonging. Shallow place in the river where oaks grow – a thought that calms me.

The name Adair was given to 33 boys and 20 girls in the US in 2016.
Adair may be listed as masculine, but I know two women who are named Adair. One was named for the Scottish song Robin Adair, where Adair is a surname. It was chosen by the woman's father because he thought it was pretty. Adair is probably derived from a phase meaning 'place of oak trees'
