Anyway to positively ID these without fruit?

These are growing wild in the woods behind my house but there is so much shade they never Bloom. I transplanted these about a month ago to see if I could get some fruit. Google Lens tells me they are black raspberries or blackberries or poison ivy.🤣 and even once told me it was milkweed. So I guess it’s a different answer for whatever mood it is in.
