Hi,
Thank you all for the help, the war record is of his son, Harry Tremaine(Pearsall) was married to Matilda Elliott (second wife) first wife was Cecilia Rousell.
I found Harry Pearsall on the 1881 census under Dearsall - if you put in Myra Dearsall born 1842 born in Oldswinford Worcestershire it should come up okay and if you look at the original it will show Harry there age 16.
On the 1871 census put in Mirah Pearsall age 29 from Oldswinford living at Upperswinford Worcestershire, then look at the original and you will see Harry age 6yrs a boy, but it has been punched up as Mary.
I can not find him on the 1891 census, or any other.
I found a ship called "Rockton" coming from Melbourne to Sydney on the 16 march 1888 with a passenger called Pearsall, so that is why we thought it might be him.
Many thanks for all your help.
