The vessel ALFRED HAWLEY official number 29015 was still owned by Walker and Fowler and registered in London UK in 1870. I assume that her marketing was in the hands of Devitt and Moore who in 1860-1870's were trading brokers for a number of merchants who owned sailing vessels on the Australia run. I note ALFRED HAWLEY is not on the list of vessels owned by Devitt and Moore. I understand she was sold to Newcastle NSW interests in the early 1880's. Her registry was closed in 1913.
To answer to the original post.
The 1870 logbooks and crew agreements of ALFRED HAWLEY are available from here
