Here are some family trees I made for my thg fic holding bright! I include a good amount of worldbuilding and fleshing out of some side characters (aka Bristel, Thom, Leevy, and Delly) in it, so I thought hey might as well draw some trees to help clarify my thinking. First, some notes on the structure:
The numbers in brackets are the characters' ages at the time of the Reaping for the 74th Hunger Games. I didn't feel like assigning specific birthdays for everyone, hence just the ages lol. Some characters' ages differ from canon in my fic: Katniss, Peeta, Delly, and Madge are all 18, Prim is 13, and Rory is 12
My use of "clan" here is super arbitrary, it doesn't actually mean anything lol
Names in quotation marks are nicknames/what they go by
Plenty of people in the older generations are dead, again I just didn't feel like specifying it unless it's relevant
Some notes on my decision-making in general:
I accidentally made Katniss and Peeta's maternal grandmothers have the same maiden names please ignore that lmao they are NOT related closely At All, it's a normal amount of distance lol
Ashwin is supposed to be older than Jubilee, not younger!! and Carson is supposed to be younger than River and Rylee (who are twins)!!!
Some of the names chosen for some Seam characters are Indian names, because I headcanon that people from the Seam can be a mix of a ton of different stuff, including South Asian
The idea that Mrs Everdeen's first name is Alyssum (Alys for short) comes from Mejhiren's fic When the Moon Fell in Love with the Sun
I continued the bread theme for Mellark names lol. Mr Mellark's first name is Nick, from pumpernickel. I also once read a fic where Peeta is of Jewish descent, which I really liked, so some of the breads are of Jewish origin: Hal is from challah (which can also be written as hallah), and Bab is from babka
In Holding Bright (which is an au, hence the variety of small changes I have made to canon lol) the Reaping takes place on June 1st (instead of the canonical July 4th), and it's also canon that the Games start exactly one week after the Reaping, so therefore in HB they always start on June 8th. Therefore, the teenaged deaths set after June 1st -- Glory Salsbury, Maysilee Donner, and Ridge Littlefield -- were all in the Games.
As explained in chapter 9 of Holding Bright, Ezra and Petunia Rainwater started a tradition of giving their kids long ass floral names lol. Their first child was relatively spared, with the name Foxglove, though he still went by Fox; their second child, Devil-in-a-Bush (or just Dev) fell in love with a woman who also just so happened to have a super long floral name, Queen Anne's Lace (though she went by Lace). All of Fox's descendants were spared from this naming tradition, to the point where his daughter, Hazelle, gave all of her children only four-letter names. Meanwhile, Dev's descendants got the longest names ever lmao: Chrysanthemum had five children: Morning Glory, Lily-of-the-Valley (aka Leevy), Stairway to Heaven, May Night Salvia, and Forget-Me-Not.
I have a headcanon that in Town they tend to give their children middle names, while in the Seam they don't (why? I don't know <3). In Town middle names came into use because they wanted to honor loved ones who have passed away, but because of the Games and all that it's considered bad luck to give your child the same first name as a deceased loved one
However, because I'm lazy I only wrote out the middle names for the youngest generation because I didn't want to come up with middle names for every single Merchant character lol
Katniss and Prim have middle names because their mother is from Town. Madge's middle name comes from Maysilee, just like Katniss's
I'm going with the popular headcanon that Katniss is indirectly related to Lucy Gray through Maude Ivory. Katniss's father's name follows the same conventions as those of the Covey (name from a ballad + a color). I had originally planned for people to only really know Mr Everdeen as Jet, hence why the family tree says Gordon Jet "Jet" Everdeen, but I have decided against that!! he went by Gordon Jet!!!
The first part of Mr Everdeen's name comes from the Scottish ballad Lord Saltoun and Auchanachie, in which the protagonist, Jeannie, is in love with a poor man named Auchanachie Gordon. However, despite Jeannie's resistance, she is married off by her parents to the wealthy Lord Salton/Saltoun; Jeannie then dies of a broken heart before Auchanachie Gordon returns and also dies. I thought Gordon is a fitting name, considering that Mrs Everdeen left her life in Town, where the wealthier Mr Mellark was in love with her, to marry the poorer Mr Everdeen
The second part of Mr Everdeen's name, Jet, comes from the color jet black; jet is also a type of coal
Some allusions to another canon character + my minor OCs:
Rooba is the name of the butcher in canon, so here she is Delly's aunt
Madge's maternal grandmother, Magnolia, has the maiden name Blackwell. She is distantly related to Maggie Blackwell, the carpenter's daughter who went missing about a decade ago
Thom’s maternal grandmother, Nomi Goodwin, was originally from Town
Bristel's mother, Juniper, passed away from complications at childbirth
Gale's maternal grandmother, Anika, has the maiden name Reeves. Gale is second cousins with Sparrow Reeves, the female tribute from 12 in the 68th Games who made a lasting impact on her district due to the brutality of her death
River & Rylee Ludlow are the 17-year-old twins who tend to pick on Madge a bit. No wonder they're related to Mrs Mellark...
Mrs Mellark's brother, Noah, died in the Games. Her other brother, Elijah, took over the apothecary shop from the Stewards after Alys ran away to be with Gordon Jet
Ivy Fairweather is the Undersees' housekeeper, usually referred to in HB as Mrs Fairweather. She and her husband probably have a ton of kids, but I just didn't feel like writing them all out lol. Ivy's maiden name is Claymore, which is also the last name of another OC, Hetty Claymore, who mysteriously died; Ivy is Hetty's like second cousin whatever-times-removed or something (aka practically a distant aunt)
