Looking for Delaporte from England Around 1800 S

Hi,
I am trying to trace any information on the Delaporte's who came out from England in 1842. I know that John Delaporte and his wife Emma ( nee Penfold) came out on the "Trusty" to Australind, Australia.
I am hoping for information on John's father, Charles and mother Mary who where born in the late 1790's.
If anyone has any information that they are willing to share, I would love to hear from you.
Thanks
Neeshia
