Hello and bless your heart! My grand-dad mentioned some Keys on numerous occasions and he was from Chandler, as was his wife, they raised their family there etc. You ARE on the right track looking in Chandler but bless your heart, I don't have a lot of information to share. My family has been gone for years or mother could and would help. My family were the Koonce and Bridge families. They were ALL from over there....BEST OF LUCK and wish me luck too! Danise
