Great presentation. One thought.  At the end of the lesson, you talked about removing the Sr. You might consider leaving the Sr. or Jr. or?? if there could be a possibility of two people having the same first and last name. I am a John Joseph Schreiber Jr.  My dad has the same exact name with Sr. after it.  If we both ran a company, you might have a reason to have both our names.  So, the Sr. Jr. would tell us apart.
