How to find the parent folder (root tree?) of the above sub-volumes ?
On this parent folder I expect to see the above sub-folders as regular
folders.
Use: btrfs subvolume show on each subvolume in turn, and link up the
subvolume uuids
If you can read python, I suggest you take a look at the source code of
btrfs-clone,
as it contains code to walk the subvolume tree of a btrfs filesysysem.
