Anent the pronunciation of the word Boho as Boe.
Boe was in the past a fairly common surname here in S.W.Scotland and indeed there are still five entries of the name in the telephone book.
There is a poem/ballad called John ABoe. The A being the Galloway equivalent of the Scottish Mac, Irish O and Welsh App.

Can anyone help---the name Boho puts me in mind of a book "The History of the Round Towers in Ireland" Is there any evidence of one of these structures in the Boho area?.
