Addition of partial CWGC records to Ancestry

Records for 560,902 out of the 1,700,000 men and women of the Commonwealth who died in the two world wars are added to Ancestry.co.uk in their new UK, Commonwealth War Graves, 1914-1921 and 1939-1947 database. The database was produced from older CWGC publications so lacks more recent information.
Despite bearing UK in the title this database includes Commonwealth cemeteries, a large number in Canada.
The free CWGC database appears to include the same information and being more complete is a preferred source.
