Thank you Siouxsie and JM
The JUNO was, in fact, the HMS JUNO which became the Colony Governor's residence in Port Jackson.
I am attempting to confirm that George Gilbert EDMONDS was on the HMS JUNO.
I have not found any immigration records for him: There is a whole lot of information about Captn. FREMANTLE. The port of Fremantle was named after his brother.
GGE was married in Sydney in 1857 and later came to Brisbane where he died in 1906.
I will keep an eye out for PRICE
