Lambsy on Family Tree Circles

Hi I am looking for any information on William Mead who came to Tasmania Australia and married Ann Fisher nee Garth in 1855 they had 2 children that I am aware of Clara Esther born 1856 died 1932 and Charles Ernest born 1858 died 1893,I believe William was born in 1827 as on his wedding certificate states him as being 28 years of age in 1855 the last thing I can find on him is on Trove for the year 1897 so I can't find when he died or how he got to Tasmania or anything on his parents also on Ancestry.com they say he was born at Gillingham,Dorset,England but I can't find anything to confirm this so any information would be gratefully received cheers !
