Aoi Hana by Shimura Takako (6 volumes, ongoing):
In a display of stellar timing, Yasuko comes out to her mom and sisters about her relationship with Fumi when Fumi visits them- without forewarning Fumi about it. Amusingly, Yasuko's family not only doesn't care, they call Yasuko out for dating Fumi while having feelings for someone else. Yasuko's older sister Shinako's bisexuality doesn't seem to be a secret to her family either. Last but not least, Fumi's friend Haruka's gay older sister Orie comes out to her family about her relationship with Hinako.
Clover by Otsu Hiyori:
Clover is a short story collection about four sisters, two of whom (Fuuka and Midori) are interested in women. At one point the second oldest, Fuuka, vents to her older sister Ichige about losing the girl she likes to another girl. Ichige's reaction is perfect: "You got your heart broken, and you never even told her how you felt. If you tell me something that pathetic again, I won't let you in the house!" Coming out isn't an issue at all in this family.
Concerto by Hattori Mitsuru, chapter 5:

Keito, in turn, starts to understand her mom more. What we last see of Keito's relationship with her mom promises further positive change.

Fu~fu doujinshi Minamoto Hisanari made, after agreeing to be Suu's girlfriend, Kina tells Suu that dating girls has always seemed normal to her because of Kana.

Gokujou Drops by Mikuni Hajime (three volumes, completed):
Yukio's parents object to her relationship with Komari since they're rich and Komari isn't (and there's that niggling issue of same-sex marriage not being legal, which this story doesn't emphasize) and they want Yukio to marry someone who can contribute to the family fortune. Thankfully, Yukio and Komari are able to be together, with the support of Yukio's aunt and brother.

Gunjo by Nakamura Ching (three volumes, completed):
In the final chapter of volume 1 of
Gunjo, the ex-wife (because she is nameless, I will call her B) of one of the leads comes out to her mom as a lesbian- and her mom not only doesn't care, she cements her place as the most awesome mom on this list. Dad finds out from mom, and he is just as cool with it. B's fate is ultimately horrible and sad, but this chapter will forever remain one of the most heart-warming, achingly poignant things I have read.
Hanjuku Joshi (two volumes, completed) + "Soft-Boiled Fujoshi" in

"Living-Room Flower" by Takahashi Mako in
Yuri Hime volume 25 (the July 2011 issue):
Jitsuko comes out to her mom Hanae and aunt Tsubomi. Hanae is accepting, but Tsubomi sputters in protest- because she has been repressing her feelings for her sister-in-law Hanae. Tsubomi confesses to Hanae after Jitsuko comes out, but Hanae seems oblivious. Because Tsubomi's confession is so freaking obvious- and feigned obliviousness is A) the easiest way to reject someone you don't want to hurt and B) less sad than the idea of Hanae willfully denying the nature of Tsubomi's feelings- I want to think Hanae feigned not getting it. It stretches credibility too much to think that she really didn't understand. Jitsuko, who doesn't witness Tsubomi's confession, stays pretty chill despite Tsubomi's behavior.
Love Flag Girls!! by Takahashi Itsumi:
In this silly historical fantasy, Princess Lucia boards the dreaded pirate Maria's ship to get the cross pendant that Maria stole from Queen Beatrice. Instead of Maria, Lucia finds the ship captained by Maria's daughter Eliana. Lucia and Eliana fall in love, and it turns out that Beatrice and Maria dated and Beatrice is just pissed that Maria dumped her. Maria returns and makes up with Beatrice, so Happily-Ever-After for everyone. ^_^
Love My Life by Yamaji Ebine:
Yamaji Ebine had a stroke of genius when she came up with
Love My Life's premise. Ichiko comes out to her dad, who then tells her that he is gay, as was Ichiko's mother. Ichiko is obviously accepting, but her head reels a bit from learning that her parents' lives differed from what she had thought.

Poor Poor Lips (three volumes, ongoing):
Ren has been out since high school, but her mom, Nei, still wants her to get married. Homophobia aside, the fact that the "ideal" spouse for Ren would boost the enormous family fortune gives Nei a strong incentive to marry Ren off. When Ren confronts Nei about her trying to bribe the girl Ren loves, Nako, to stay away from Ren, Nei cuts Ren off. Ren only agrees to return home and do what Nei wants on the condition that Nei will erase Nako's never-ending debt. Ren's father, Akio, can't change Ren's situation, but he does support Ren and helps Nako get a job as a maid at Nei's house so Nako can reunite with Ren. What will happen!? Dun dun dun.

Rica'tte Kanji!? by Takashima Rica (omnibus volume coming out soon):
The "More Rica'tte Kanji!?" chapter in
Yuri Monogatari 4 shows its protagonist Rica coming out to her parents and little brother during her high school years. Rica's dad is a lot more accepting than he first appears to be, Rica's mom has no problem with Rica's sexual orientation because she's bisexual (she even goes starry-eyed remembering her first time with a female sempai in high school) and, best of all, Rica's gay little brother feels like he can come out sooner because of her. Awww. ^_^
Sasameki Koto by Ikeda Takashi (9 volumes, completed):
Our protagonist Sumi comes out to her dad in volume 9, but I won't spoil how that goes. Sumi's love interest Ushio is out to her older brother and grandmother from the beginning of the story. (Her parents died years earlier.) Her brother is understanding, at least. ^_^; Good thing she's able to live with him. Her grandma does comes around by the end, though. Additionally, our side couple Tomoe and Miyako are out to their families throughout the story.
"Spicy Sweets" in
Butterfly 69 by Natsuneko:
Coming out to one's parents is nerve-wracking enough. But coming out to your mom when she's the leader of a yakuza syndicate? That's what Yuu does, and her mom isn't pleased. Despite everything, this story ends happily.
"That's Why I Sigh" in
Yuukan Club volume 14 +
Maya no Souretsu by Ichijou Yukari:
Reina, the protagonist of Ichijou Yukari's
Maya no Souretsu, comes out to her mom about her relationship with another girl, with...less than happy results. Btw, I like
Maya no Souretsu. It's tragic, but in a stylishly over-the-top Gothic/film noir way, and I could see the story playing out just as tragically (given the skeletons in Reina's family's closet, Maya's revenge plot and...uh, certain hidden family ties) if Maya had been a guy.
Decades later, Ichijou Yukari re-visited coming out in the humorous, upbeat "That's Why I Sigh," which features a teenaged lesbian who is in love with her best friend. Mako serves drinks at the okama bar where her "dad" works as the Mama. ("Mama" = the term given as a nickname to the head okama at okama bars.) Mama is weirdly gung-ho about the idea of Mako getting a boyfriend, but is on the same level of pushiness as that ineffective great auntie type who lightheartedly ribs you about when you'll finally get a boyfriend even though you express no interest in it rather than, say, someone like Ren's mom in
Poor Poor Lips. Even with Mama's not-exactly-ideal response to Mako's lack of interest in men, "That's Why I Sigh" is a sweet coming out story.
"The Female Body" by Konno Kita in
Yuri Hime volume 22 (the January 2011 issue):
Sumi has been in love with Kaori, her philandering brother Ryou's wife, since they met. After things fall apart between Kaori and Ryou, Sumi admits her feelings to Kaori and they get together. Sumi is afraid that Kaori isn't as serious about their relationship as she is, but Kaori tells Sumi she's in love with her and accepts Sumi's marriage proposal in a public park. They tell Kaori's son Takkun that they're getting cake on the way home to celebrate the birth of their new family. ^_^ Squee! I wish Konno Kita would draw more stories for
Yuri Hime.
Takeuchi Sachiko's
Honey & Honey and Chi-Ran's "Her Temptation" one-shot in
Shoujo Bigaku technically don't count because their protagonists do not come out to family, but I still highly recommend them for their explorations of what it means to think about coming out to family.
Know any examples that I've missed? Let me know!
