Jeremiah came to Ireland with Tea Tephi, King Zedekiah's Daughter and also the Lia Fail, Jacobs pillar. All our Kings and Queens were anointed on it as were the Kings and Queens of all Scottish and English Monarchs.

For those interested in prophecy, the book of Ezekiel talks about these events, saying:
21:25 And thou, profane wicked prince of Israel, whose day is come, when inequity shall have an end,
21:26 Thus saith the Lord God; Remove the diadem (sovereignty), and take off the crown: this shall not be the same: exalt him that is low, and abase him that is high.
21:27 I will overturn (1st), overturn (2nd), overturn (3rd), it: and it shall be no more, overturned (4th) UNTIL he come whose Right it is; and I will give it him - Shiloh (Gen. 49:10).
To understand all the details of the Stone's full history, the reference link above will need to be looked at, but three of the overturns have already come and gone, and the fourth overturn began in 1950 when the Stone was taken from Elizabeth, but has not been completed yet.
Overturn 1: From Jerusalem to Ireland (Hill of Tara) in 6th century BC.
Overturn 2: From Ireland to Scotland (first Argyll, then Dunstaffnage) around 5th century AD.
Overturn 3: From Scotland to England (London - Westminster Abbey) in 1296 AD.
4th and Final Overturn: Began when the Stone was taken from Westminster Abbey in 1950 AD.
