Mrs Thing's real name

Does Kingdom ever remember Mrs Thing's name? In episode 1.6, when she's almost hit by a lorry, Lyall asks what her name is, and it's clear that Kingdom doesn't know - or can't remember. But he refers to her as 'Mrs Thing' even to Gloria, who never (so far in season 1) doesn't ever mention her by name or correct him.

So does he ever remember her name? Does anyone know her name? Or is her name something rude and embarrassing so he doesn't want to say it?
