See which branch a branch was originally created from?

Question

I have a branch that was created from an existing branch. However I don't remember which existing branch was used. How can I find out which branch this was?

A given branch could have _multiple_ parent branches, e.g. `master` -> `feature` -> `feature feature` — Tim Biegeleisen, Jul 20 '15 at 16:10

Branches do not have parents.

Commits have parents.

A branch name is a strictly repo-local temporary label for a currently-particular commit.

You can achieve the effect you want locally with local tracking:

git branch -t testing master

will set branch testing up to track branch master, so a git pull with that checked out will merge from that by default, git rebase will use that by default, and so forth -- and git branch -avv will show any configured tracking.

Any correspondence between branch names and configuration in your repo and any other repo is just convention and collaboration in action.
