I am sort of trying to do the same thing you are. I thought it was interesting that your great grandfather was Earl Maggard. I have a great uncle named Earl Maggard. Earl was the blacksmith at the Shepherd Of The Hills theme park and play in Branson, Mo. before he left to build horse drawn buggies and wagons at his home. Earl also makes 'white lightning' and usually has a couple of Mason jars with a clear liquid in them sitting around.
I haven't seen Earl for a few years. You have me thinking I should visit.
