Right now on Ebay (item #391538894072) there is a CD titled Best of Celtic Woman. There is no track list. Publisher is shown as P&W Partners, Ltd. Date shown is 2008.
There are also other CDs titled Celtic Woman. One is a Christmas album.
They are from the UK and seem unrelated to "our" CW.
Just found another: Best of Celtic Women (yes, with an E) - from 2012 / no track list.
These cds are unrelared to CW while the one on wikipedia obviously is by "our" CW ladies
