Three different women who used to be strangers discovered by chance on Twitter that they are cousins and their Twitter conversation has gone viral.

It began when Twitter user @nooksikamui shared a photo of her great-great-grandmother named Atelaite Fusikaunanga. 

Another Twitter user, @letaua_, who travelled to Tonga for the first time last October realized that the photo looks familiar. During her trip to Tonga, she had seen a similar photo of the same woman in her father’s house.

She shared the photo she found in Tongo and said the same woman is her great-great-grandma.

At first, in error, she said the woman is her father’s older sister but corrected it and stated that she’s her great-great-grandma.

But, it didn’t end there. A third woman, @champagnenani_, saw the tweets and revealed that she’s her great-great-grandmother too.

“What a small world! That’s my Great great grandmother too! Atelaite Fusi who my paternal grandmother is named after. I’m flipping out,” she wrote.

She added: “I’m so mind blown at how we all share the same Great-great grandmother the same picture – three different times I love this!”

@nooksikamui, who shared the photo of the woman first, was excited to meet her cousins and she retweeted their tweets.

Twitter users are now calling for all three women to organize a hangout.

Below are a few Twitter reactions.
