I've done some digging around and been shown the source docs. It seems Henry, born 20/3/1821 was baptised 18/7/1821, he was born at Mawnan. He married Elizabeth Inch at Kenwyn in 1852, but he had already previously come to AUst on the Navarino in 1848. It is a mystery why he returned, married Elizabeth and came back as an assisted passenger. Charles was witness at his wedding to Ellen Holden in St Kilda in 1854. Henry's first child Edward married Charles daughter Grace Gertrude ( they had a number of children die as infants an "cousins" is written on the death certificates.
Henry was a substantial landowner in Highton Geel, where he is buried, and where I grew up. He was also a kep player in setting up the Wesleyan Church in the shire of Barrabool.
There are legal papers regarding his inheritance form his grandfather Richard, as William's inheritance was only for his lifetime it seems.
Apparently in the 1841 census Henry was with his brother John at Trevisa in St Enedor.
Unfortunately the source docs are not mine so I cannot send them on.

Scott Johns.
