Barbara (Bakw) caught me in several errors on this one and they have been fixed.
I changed the first parpagraph - where I have in about around 10th century - it in reads in the 10th century.
Made the same ;mistake in the second paragraph with in about and now it reads around the with "in" removed again.
Then in the last paragraph I started with quotation marks that don't belong there - I have removed them!
Thanks everyone for helping me spot these typos. Makes my books so much nicer when they are caught!
