It strikes me as unlikely to the point of impossibility.
On the other hand, Mac Onlea could easily come from the
reduction of Mac Dhonnshléibhe.
That is extremely disappointing to me, but I appreciate that you are candid.
I think I understand why the "Dh" and the "sh" in Mac Dhonnsliebhe is
lenited, but I'm a bit confused about the rules for muting of the "bh". Is
there a standard rule?
