With the help of Rootschatters via the handwriting section
https://www.rootschat.com/forum/index.php?topic=881735.0, Richard Ryland was not related to T F Warren but a much respected friend. I misread 'much' as 'uncle'.
Richard R was a beneficiary, as was one of his daughters, Emily, if he died, but nothing about his daughter Charlotte benefitting.
So Edward Ryland the conman was likely inventing a legacy for Charlotte in that advert he posted.
None of which helps with Flora Wayland's birth place or who du/da Costa was.
