Dear Cathy, just a quick note to say the Glendennings (most common spelling) originally came from Glendinning (glyn din gwyn 'glen of the fair hill', evidence that there was a local enclave of Britons after the Scots invasion from Ireland) a tiny place in Westerkirk, Dumfriesshire, and settled in Antrim and Tyrone in the early 17th century, where the name remains common. Adam de Glendonwyn is recorded in 1286 (C.F. Black 'The Surnames of Scotland', New York, 1946). Other variants are Glendening, Glendinning, Clendenin, Clendening, Clendennen, Clendenon, Clendinning, and Clindening (the Cl- spelling often in Ireland). Due to Irish immigration the early Glendennings of Liverpool (who had presumably come south from Scotland) were joined by Clendennins and Clendennings. I expect you know that the full name of Oscar Hammerstein (of "Rogers and Hammerstein" fame) was Oscar Greenley Clendenning Hammerstein II! Regards, David
