(CNN) -- For Jo Sharpton, it started so early that she can't quite recall how long ago it was.
She does have a specific memory of enjoying the works of J.R.R. Tolkien at age 7.
"I remember that my sister and I saw the Rankin-Bass animated version of 'The Hobbit,' and then had the special deluxe Double LP Edition," she said.
"We listened to this dozens, if not hundreds, of times, memorizing every piece of music, every word of dialogue, every special effects sound. At such a young age, I was immune to the bigger picture of Tolkien's world -- it was enough for me to enjoy the kids' story for what it was."
With 75 years of history to draw on, and an official Tolkien Society for 40 of those years, countless fans like Sharpton have begun their journeys with stories like this. In so many ways, Tolkien fandom has become a family affair.
Now an adult, Sharpton sees this week's release of "The Hobbit: An Unexpected Journey," as a chance for what she calls a "family reunion."
The retail worker from Atlanta will be joining 50 of her closest friends in Tolkien fandom, all traveling to Pleasant Hill, Kentucky, to see the movie as a group.
The town's Shaker Village holds a special place in the hearts of those in her large group, because they have held two gatherings there since 2008.
They're called "A Long Expected Party," a term based on the first chapter of "Fellowship of the Ring." The Shaker Village, once home to a 19th century religious community, was seen as the perfect stand-in for the Hobbits' Shire from Tolkien's stories.
"We had over a hundred attendees, for three days of music, laughter, love and 'Fellowship,'" says Sharpton of the first gathering in 2008. "We thought of ourselves as the anti-(fan) convention -- no hurried crowds, no standing in lines for hours, no cold, lonely hotel rooms."
The lack of amenities was seen as a plus: "There was very little technology present -- some of the houses and rooms did not even have TV's, Internet was only available in a couple of places, and there was little to any cell phone reception. And no one cared. In fact, it made the magic all the more real. We were in the Shire. We were living in Tolkien's world, if only for a few days. "
They plan to do it all over again in 2014, but this weekend's smaller gathering will be special as well. As at "A Long Expected Party," many of them will attend the movie in costume.
"It is something that most of us have been looking forward to for months."
Sharpton really started to appreciate Tolkien's work in her teen years, and was especially drawn to the character of Eowyn, a hero who dresses as a man in armor to fight in a battle in "Return of the King."
"(I admire) her courage, her desperation, her need to love and be loved, her desire for honor and glory 'far above the mean things that crawl upon the Earth,'" says Sharpton. "I began to write stories about her as a teen, using her as a character of her future self, having finally found love and honor but always yearning for that little bit more."
Like Sharpton's Eowyn, a particular Tolkien character captured the imagination of Nadine Palmer of San Antonio: Arwen, the elf portrayed by Liv Tyler in Peter Jackson's series of Tolkien films, starting with "The Lord of the Rings."
She, too, plans to attend "The Hobbit" in costume, but she has taken it a step further: Costuming is now her business as well.
Jackson's "Fellowship of the Ring" captivated her as a teenager in 2001 and she immediately sought out Tolkien's work in the library. But the costumes also stood out to her in a big way.
"I made it a point to learn how to sew costumes due to how gorgeous the costume design was in this film," she said.
"I made a costume of Arwen's that was five sizes too big, made from the completely wrong fabrics, and by all accounts was horrible! But I loved it. I was so proud that I did hand-beading on the sleeves and I had grown my hair out to an elven length. And I had elf ears!"
In 2004, she went to Atlanta's Dragon*Con and spent time with a cosplay group called "Arms of Middle-earth." That's where she met "a cute guy dressed as 'behind the scenes Legolas.'"
She and her now-boyfriend work on Celtic Ruins costuming, and, of course, have grand plans for "The Hobbit" release. "I've just completed a nearly screen-accurate Bilbo for a friend who looks, creepily, like Martin Freeman! Handmade down to the buttons."
Costuming isn't the only thing Tolkien fans have in common. It's quite literally a family affair for those who pass down a love of Tolkien stories from generation to generation.
There is live-action Tolkien role-playing, where fans re-enact scenes from the book or create new ones.
In preparation for the movie, fans are re-reading the book, creating flow charts identifying dwarves versus hobbits, putting on trivia contests, updating their cosplay progress, and that old standby, posting Instagram photos of movie tickets.
With "The Hobbit" trilogy expected to be another box office behemoth, Tolkien fandom can only grow from here.
