There will be _no_ way.  It is simply impossible.

    $ git checkout -b my-new-branch origin/somerandombranch~27^2^2~23

is a perfectly valid way to create a new branch.

You would probably want to re-think in a bigger picture, _why_
you would want to find such information, in other words, how you would
want to use the information (if such a thing were possible) to solve
_what_ problem.  That true problem you did not mention (and assumed that
"the remote branch the branch was branched from" would be a good tool to
solve it) might have a better solution.
