I am jus' a 15 year old kid who is listening to AC-DC right now but I as most other kids are am interested in my roots so I signed up. I am John Tierney 3rd, I am devoted to my roots. I researched a few things, finding out we have at least three different coats of arms. While I am sure we are Gaelic, I am wondering if it is also a mixture of another name. I came here to ask about Clans, I searched alot and apparently some famoly members in australia, america, europe, and other places in the world have made their own clans under the name of the Tierney. I am just curious about that. Thanks ^^!
