Constellations on Gemini Twin faces

My brothers are identical twins called Ross and Kevin. Throughout their lives they have used the moles on their faces to help people identify which is which. Ross had Orion's belt on his right cheek and Kevin had the Bear/Plough on his left cheek. One evening Kevin was researching our surname, McMahon, and discovered that the name came from the Mahon tribe in Ireland, the leader of which was named after the Big Bear in the sky. Further research led to the discovery that our mother's family name, Pengilly, came from a connection to Orion, the Headhunter. This definitely piqued our interest so I overlaid these constellations on pictures of Ross and Kevin's faces and we were stunned by the accuracy of the placement of the moles and the primary stars in each constellation. Even further than this, we realised that there were a few other major stars in the constellations that we discovered actually existed on their faces as well! The fact that they are Geminis as well as being identical twins also adds interest.
