Well, I know 'Meade' comes from 'Meath' (reminder: pronounced the same, with a 'd' sound), but where does 'Meath' come from? Any chance it has a Proto-Indo-European root (since I'm back into PIE these days)?
Meath (/ˈmiːð/; Old Irish: Mide IPA: [ˈmʲiðʲe]; spelt Midhe in Modern Irish) was a medieval kingdom in Ireland for over 1,000 years. Its name means "middle", denoting the fact that it lay in the middle of the island. Kingdom of Meath
mid (prep., adj.) 
O.E. mid "with, in conjunction with, in company with, together with, among," from P.Gmc. *medjaz (cf. O.N. miðr, O.S. middi, O.Fris. midde, O.H.G. mitti, Goth. midjis"mid, middle"), from PIE *medhyo- "middle" (see medial (adj.)). Online Etymology Dictionary
Sure enough: from PIE (*medhyo-) down through the Celtic side of the Indo-European family to
Old Irish
:-)
