Im making a book about 2 guys living throughout the entire 20th century, does anyone have any advice?

They were born in the year 1900th and die in 2000th. For the majority of the book, they hate each other. There names are Ace and Foy, it's within America

I don't want to give too much away because I'm still doing notes and research but we follow every single year in the century. They were both abandoned at birth in the hospital, a nurse took care for them.

We do follow this nurse for a bit, since we our main character are babies, the nurse dies in the late 1900s and we follow Ace and Foy as they become child miners.

They start a group with the other kids to get out of there and start working on the side doing jobs for different people. This starts to become a gang and they become mobsters. They make enough money to leave the mining job and get a hide out above a dress store.

Some of the guys in the gang, do go to ww1 and die, I'm still not sure if I want Ace or Foy in ww1 or not.

1920s, they become a pretty well known group but in the late 1920s, Ace betrays the group and leaves. Most of them gets arrested, Foy stays in jail for a little amount of time before hes released. He's already rich because of the amount of jobs they've done.

This also takes place on the west coast and during the 1950s, it goes into the east Coast.

There are a lot of characters, as time goes on we follow other people that revolve around Ace and Foy, multiple storylines and changes.

I've made a huge list of media to watch to really immerse myself in every decade. The list is long to cover 100 years, I have to watch multiple films/tv to cover a year.

The list for the 1970s is just ridiculous, I have to watch the wonder years, since the later seasons are 1970-1973)

Mary Tyler moore show (1970-1977)

The deuce season 1 (1971-1972)

There's johnny (1972)

Sanford and son (1972-1977)

The kids are alright (1972-1977)

Quarry (1972)

Licious pizza (1973)

I'm dying up here (1973-1974)

The runaways (1975-1977)

SNL (1975-till 2000)

Swing town (1976)

That 70s show only season 1 to 5 (1976-1978)

Dazed and confused (1976)

Charlie's angles (1976-1981)

There's company (1977-1984)

The deuce season 2 (1977-1978)

Junior high (1978)

Dallas show (only for 1978-1980)

Mind hunter (1978-1981)

As you can see a lot of this stuff overlaps, so I got watch the shows between the movies. The other decades are way easier, it's the 70s that has the most media and the most that overlaps.

You might think this is unnecessary to watch media that takes place through the entire 20th century but I wanna feel like I'm in the decade to immerse the characters and be accurate.

There's also a real focus on media, on entertainment and fashion. Ace and Foy don't really get into media untill the 1930s, but even before that there base was above a dreas shop. I'm the 1930s, Foy gets more into Hollywood and making films, while Ace opens a news paper stand

Also Foy has multiple partners thoughout the years and Ace sticks with just one

The decade that I have the hardest to find media is actually the 1900s, there's a big gap with media. Not a lot of things take place with in 1900s.

I also wanna focus on someone young within every decade, so we get a feeling of what it's like growing up in that decade. There's a focus on nostalgia too, multiple people get nostalgia for the past. Especially Foy in the late 60s, crying to a hippie because some woman looked like a flapper from the 1920s.

Eventually when this is finished, your gonna feel like you've lived 100 years
