Here is the passenger list
http://www.theshipslist.com/ships/australia/johnbanks1855.htmLooks like you have the wrong parents for William. I note you initially say William Matthews ROWE was born in Madron in 1856 yet this William Matthews ROWE was born in Paul in 1829. This William Matthews ROWE was aged 45 in 1874 when he married Jane LAWES so this fits perfectly. These are certainly the parents of Henry Stanley ROWE.
William Matthews
