WikiTree
WikiTree is a collaborative 'single tree' genealogy site. Lots of people relating to Fremantle are represented there, and anyone can contribute more. If you edit on either site, please consider keeping the other up to date with any changes (although generally, we've been adding more detailed biographies here on Freopedia, and only adding basic birth and death data on WikiTree).
There is also a tool at https://wabmd.nfshost.com that can be used to link more.
