Kyle as used in Ireland means, from the straits, or the narrows. My great grandmother, several generations back, immigrated from Ireland. Her name was Mary Kyle. Her son named his first girl Kyle and it has been a girls name in our family for 4 generations before. Me and my daughter and granddaughter both have the name as a middle name. I hated the name at first, because no one in the South can pronounce it correctly. It rhymes with smile, also vile, as someone else said. I like smile better. Until I was in high school, I had not known anyone else with this name, until I met a boy whose last name was Kyle. Since then, I have only met a few women named Kyle, but many men and boys. These days, couples are naming their children gender crossing names. In college, people told me it was unusual and they liked it. I am unique, so I thought that was great. Now the name is hardly unique. I still love it!
