I looked for any other reason for this one, but, it appears to be a family thing.
His Daddy is Birdstone and his Mommy is Mining My Own.
Makes sense.
I have a pedigree Basset Hound, though he’s strictly low-rent, LOL! His mother was ‘Sophie La-Di-Dah’ so I named our dog ‘Sophie’s Choice Rufus’ on his papers, but he goes by, ‘Rufus’ or ‘Doofus’ or ‘G@ddamit Dog, Git Over Here!’
I thought naming horses might be for similar reasons. :)
