Constance, I checked my database but could not locate a Hubert Cannady however, that doesn't mean we aren't related. This just means I am not showing your direct line yet. It could be, I have info on your great grandparents or great great grandparents but just not your grandparents.
What I need from you is the earliest person in your Cannady line that you have a birth and death date on, their complete given name and where they were born. Then we will see if we can make the connection.
Also, in doing research look for the different spellings of Cannady. Over the years the following has been found: Canady, Cannady, Kennada, Cannaday, Kanada, Canada, Kinada, Kennedy and etc.
