The Gilded Age seems to me to be an under exploited era. There is Martin Scorsese’s “The Age of Innocence” based on the Edith Wharton novel. Another Edith Wharton Gilded Age novel “House of Mirth” was adopted as a movie in 2000.
British TV concepts don't always translate very well to US TV.
Often they do, but sometimes they flop.
Also, the headline needs work: Cynthia Nixon and Meryl Streep had a daughter?
There are some fun Hollywood musicals and comedies set in the period (or near it) such as Meet Me in St. Louis, On Moonlight Bay (and a sequel By the Light of the Silvery Moon and The Happy Years. In all of those films, the father is played by Leon Ames.
It's probably under-exploited because it is seen as "too white".
