Frances Coakleys "A manx Notebook" at
www.ee.surrey.ac.uk/Contrib/manx/index.html has a few references on Clucas.
A out of print book The Frail And the Fleece(I think) has a reference,but I havent seen it yet.
My Clucas is associated with the Clucas Laundry(1920's), but because she came to South Australia alone, I havent found out much about her. - I think my Catherine Elizabeth Clucas was born 1875 to James Clucas.
