Hello. I believe the Charles Howard that you are referring to arrived on the 'EUPHRATES' into Sydney in 1855. I am doing research on my ancestors the Jacksons (specifically Joseph). Charles Howard was a witness on Joseph's marriage certificate at Geelong in 1859. Joseph Jackson also came from Barley in Hertfordshire and was a gardener at Buninyong. I shall be looking up some records at the NSW State archives sometime in the next month or two and was going to get a copy of Charles Howard's shipping record. My email address in
castrobaglin@optusnet.com.au. I am happy to email you a copy when I get it.
regards Carol Baglin
