A fellow researcher passed this site on to me and it has some immigrants by the surname of Chamberlayne.
The account of the Ship itself is quite tragic.
Then, there is a lengthy list of passengers. If you want to find the Chamberlayne surname quickly, hit Ctrl and f and a search box will pop up. Type in Chamberlayne. It will go to the first family. Hit search again and it will go to the next time Chamberlayne is listed.
Here is the URL of the site:
