Joe

Answer 2

My dear, which Jackson family are you talking about?  Jackson is an extremely common name.  When surnames were taken or assigned, many men whose father was called Jack became Jackson.  

Are you talking about Stonewall's family?

Are you talking about Andrew's (Old Hickory's) Family?

Are you talking about the Jackson Five or whatever you call them?

You need to be clearer in your question.
