They steal the names they've seen somewhere, think they sound fancy but don't know how to pronounce them. Thus, "Jacques" becomes "Jac-quees". Same for "Marquis" = "Mark-quees."
I do enjoy the names of sows who were shat out when the trend was to name female niglets after their incarcerated or MIA sperm donors and we got true abominations like "Stanesha" and "Johnesha". Just take the baby daddy's name and stick an "esha" on the end.
Stupid goddam idiotic mammy sows.
