Hoste Island has it's name from William Hoste who at one time
was Nelson's cabin boy and later on in his navy career went on to
travel the Americas and discovered this island. I've only found
this out recently because I I've been learning about my family tree
and Hoste is my great great great grandfather (i think that's
right!)
Hope that is helpful, it's not very detailed as I don't know
very much.
