I've been stung a few times by the OP's silence and/or lukewarm responses (no pun intended), so this time I only asked a direct question, but unfortunately someone else wasted their time and repeated the information that the OP is already aware of.
I could have given the OP some corrections and actual data re the Ernst children, but it is obvious that it would be another case of casting pearls before swine, so I'm keeping that data to myself this time.
It is rather amazing how all our comments seem to be like water off a duck's back ...
