Casper & his "brother" Magic's genealogy.

Fantastique !!
Never heard before a dog having a human surname,
like that of Kshitimohan SEN, Amartya SEN or Nandalal BOSE !!
There must be some psychological reason for ascribing these names &
the genealogical relationships, but from biological & genetical points of view,
the whole idea is NOT tenable!
Do excuse me, please !!
