Hi
Amelia's birthplace in the 1851/61 census is given as Dedham.
From the parish records for St Mary The Virgin, Dedham, baptisms
Amelia Buck, daugh of Henry & Ann P?

? bap 30 Dec 1794.
Can't make out the surname in these records either as they are very faint, there are more baptisms for the same parents in the records however the writing is faded with those aswell. I have looked for a marriage in the parish for Henry & Ann hoping that the handwritting would be better but can't find one.
Could the name possibly be Pickess ?
