Irene Adams, and her “doppelgänger” (is a look-alike or double of a living person, sometimes portrayed as a paranormal phenomenon) Niamh Geaney, tracked down each other using Twinstrangers.com, a website owned by Ms Geaney.
The two of them then decided to see if their almost identical resemblance of each other was more than what meets the eye. It has been scientifically proven that the girls are not sisters, and have no biological relationship to each other, meaning that they are not likely to even be related in any way to each other.
After scientific analysis the results shows that there was only a 1.1 percent chance of them being half-sisters and revealed that there were no other signs traces of them being related, even though they look like identical twins, and both being Irish.
They even went as far as tracking down their ancestral decent, dating back 20 000 years ago where it was found that Niamh’s ancestors originated from South West Asia, whilst Irene’s where from Mesopotamia.
Niamh, 27, said: "We both always had this natural curiosity to find out if we were related at all. "It was the comments on YouTube and social media that finally made us go for the test, everyone was just so curious and wanted us to prove we weren't related. "I mean we just wanted to know if there was something more behind us being identical, I thought at least 200 000 years ago there might have been a connection.
"When we got the results we weren't too surprised, we didn't expect anything to come of it really, it would have been really special if we had but the whole point of a doppelgänger is that you're not supposed to be related."
Niamh now spends her time assisting others find their doppelgangers after having found 3 of her doubles so far. She started the project with her friends and since then has already found other lookalikes Kren Branjgan and Luisa Guizzardi prior to meeting Irene.
"I'm so lucky to have already found three of my doppelgängers and they're all such awesome girls too” adds Niamh. "Anyone who meets someone who looks identical to them should take a DNA test if they're curious - I find it fascinating that there could be more to it than just looking the same”.
The whole DNA test was so exciting for us; just the possibility that something was going to come of it was really cool.
"I think I might try and do another test with my other doppelgängers to see if there's anything there - we're supposed to have seven people in the world who look identical to us so my main focus is finding my other four."
“The Twins”, Niamh and Irene found the thought of somehow being related to each other quite fascinating however, they are still glad to know that their almost identical resemblance is a mere coincidence. The 2 now reside in Dublin, Ireland.
