Have you tried the following command?

git branch -a --merged my-feature

It will print a list of all branches (local or remote) whose tips are reachable from (i.e. ancestors of) the tip of my-feature. If you're only interested in local branches only, you can want drop the -a option.

As an example, if your repository looks as follows

A -- B [branch1]
      \
       C -- D -- E [origin/HEAD=origin/branch2]
        \         \
         \         H -- I [HEAD=branch4]
          \
           F -- G [branch3]

Running

git branch -a --merged branch4

will print

* branch4
remotes/origin/HEAD -> origin/branch2
remotes/origin/branch2
branch1
  • Why branch4? Because branch4 is trivially reachable from itself.
  • Why remotes/origin/HEAD and remotes/origin/branch2? Because they both point (indirectly and directly, respectively) to commit E, which is an ancestor of branch4's tip, commit I.
  • Why branch1? Because it points to commit B, which is an ancestor of commit I.
  • Why not branch3? Because it points to commit G, which is not an ancestor of commit I.
