I have always called the Uilleann Pipes the Uilleann Pipes but I have only ever spoken English because that is the only language I know.

Now it may be that somebody sometime called tha instrument another name but I have never heard or read such a thing so I don't know except what some smartass here tells me.

In the history of the Bagpipe which used be on the internet it said the Uilleann Pipes evolved from the Cuislean Pipes which in turn evolved from the Pib Mhor.

They use the term evolve in its normal sense. Thus the Pib Mhor had drones but was blown, the Cuislean has drones but was bellows blown while the Uilleann had added 'regulators' in the fashion of other similar continental instruments. I suppose that would be as Mr Mick explains above.

Whether the locals called it a Honda or a Ford is irrelevant what matters is that it was and is called Uilleann by most of the people who talk about it today.
