Never knew this about yew trees.
Every Irish yew in the world, in every churchyard from Dublin to New Zealand, is a cutting taken from one tree found on a Fermanagh hillside.
Around 1767 a farmer named George Willis is said to have come across two odd yew saplings on the limestone slopes of Cuilcagh in County Fermanagh. Instead of the low spreading shape of an ordinary yew, they grew straight upward in a dense dark column. He kept one for himself and gave the other to the landlord at Florence Court, and the Florence Court tree is still standing.
The mutation is female and it does not come true from seed, so the only way to make another one is to take a cutting. That is exactly what happened, over and over, for two and a half centuries, until the descendants of that single tree stood in graveyards on every continent where the language of the parish register was English.
The columnar yew in your local churchyard is not a variety. It is a clone, and it is Irish, and it is all one tree.
