My parents and siblings all have names that begin with the letter "J." My step-father's begins with a D and my Step-mother's begins with a "L".
MH's name, his dad's name and all his siblings also begin with the letter "J". However, his mother's name is a 2 part name with the letters D and L. (Donalee)
So basically, both me and MH all have J's with the exception of D and L.
