Thank you Kent and Lin. I called my friend at the nursery where I got these two Azaleas. He said that they are un-named hybrids using native stock and grown by a local (in state) grower. He said that is why they were tagged "Azalea deciduous Pink" and "Azalea deciduous Yellow" and had basic growing info included. The grower only had a few of each and they all showed varying traits of the parents, but R austrinum and R canescens are included in the lineage but he is not sure at what point.
From what I was able to determine from my own researching, Southern native rhododendrons/azaleas are a rather "friendly" lot and there is quite a bit of cross pollination which accounts for the diversity in color.

I think that solves both of these threads... I have a lovely pair of deciduous azaleas that like morning sun, dappled shade and bloom in late March to mid April.
Again, thanks to you both.
