Occams Razor

Question: My character's family has a distinct tattoo, and our group's Roma clan has its own as well (which I happen to have found on a temp tattoo website); would it be helpful for plot to have the same tattoo(s) on hand in case someone from the family makes an appearance? I ordered a bunch, and since they're pretty darn cheap, I can probably spare a couple without issue!

I'd say that the chances of seeing such a tattoo dramatically increase if you provide them.
