How old (roughly) are these characters supposed to be?

I've watched the entire series a couple of times. But i think there is good hint factors into the characters.

We know that in 1981 - Fay Summers & Her assistant Wonda (later becomes Wilhelmina) was at Studio 57 with Warhol and the father of Amanda Tannon.

During this time - the following im guessing would be around
Claire Meade - 35
Bradford Meade - 35
Fay Summers - possible in mid to late 40's
Wilhelmina Slater - was the young say 20 something assistant

The show takes play 25-29 years later from that event so
Claire - was 60-64
Bradford - was 60-64
Fay Summers - dead but would of been 65
Wilhelmina - 45-49

Amanda Tannon - born 1981/1982 - making her (aged 25 to 29) show ran 2006-2010
Marc St.James - was probably slightly older - im guessing (27 to 31)

Betty - she studied at college so probablly in school till 18 then 3 years of college im guessing shes 21 by final episode of the series she would of been 25

Her father - probably same bracket as Claire and Bradford putting him 60-64
Hilda - being the older sister and had a teenage son im guessing 27 to 31
Justin - aged 15 to 18 by the final episode.

think this pretty much sums up the ages of the characters.

Like in the old post I just bumped, Betty was born around April 23, 1984. That made the character 22 to 25 and she had her 26th birthday a few days after the last episode aired.

Happy Birthday Betty and America!

In the Feys Sleigh Ride episode they talk about Claire burning all of the Mode copies of '86, Daniel mentions that he was twelve when this happened, so that makes his birth year 1974, so during the show he went from age 32 to age 36. Betty is said to be 25 I believe?
