My birth name is Ellen and I am Irish. At school we used the Irish version of our name and from early childhood I was told by teachers that the Irish version of Ellen is Eibhlin. So I have always used the name Eibhlin, pronouncing it Eileen. I have never heard of the name Lean before, though I think it is prettier than Eibhlin. Here in Ireland it would be pronounced 'Lane'. I am confused now as to the Gaelic version of Ellen I will use.
