I've heard "father" from some but never "son". I first learned the
terminology over 30 years ago reading Roland Gelatt's "The Fabulous
Phonograph", and in both his and Oliver Read's nomenclature it was:
1. Original wax (or lacquer) recording is the master
2. The metal negative plated from the master is the matrix
3. The metal positive pulled from the matrix is the mother
4. The metal negative made from the matrix is the stamper
And these are the terms I have been using since about 1974, when as a
lad of nine years old I was first bitten by that wheezy apparatus that
sounded like a parrot with a cold in the head.
