Eight is Enough

Question

My wife and I are expecting our 8th child very soon. she is obsessed with patterns and named our first six children (all girls). In order, they are named for:

1. A super-villainess whose alter ego is the wife of an Advertising Executive.
2. An air freshener.
3. A blue-haired woman who needs to clear her throat and get checked for jaundice.
4. A petulant municipal worker in a small Indiana town.
5. A bride-to-be that has had trouble with her maids and very recently has been mistaken for her younger sister, #6:
6. A suburban housewife who was very protective of hairy rodent wildlife.

Seeing this pattern and hoping to hurry things along, I named our seventh child (the only son so far) after:

7. A serial killer that likes hockey.

We're looking for potential names for our eighth (and final) child of as-of-yet unknown gender that will fit the pattern. Can you offer any viable choices?

_{(First answer that fully explains the pattern and gives a viable candidate name for #8 gets the win.)}

Answer 1

1. Betty (Mad Men, played by January Jones)?

2. … Febreze??

3. Marge (The Simpsons)

4. April (Parks and Rec)

5. Lillian (Bridesmaids, played by Maya Rudolph)

6. June (Leave It to Beaver)

7. Jason, covering July August September October November

so we’re looking for a gender-neutral name

related to December and a movie, TV show, or air freshener.

I’m having a lot of trouble with this one, but

Dee fits in nicely after Jason. Relate to Gregory’s Girl, a calendar-y name for a film.
