Hmm. Traditional provenance isotopes (eg Sr) probably not great for such fine grained differences. But thinking about diagenesis at the micro/trace element level might be useful. Look for marker trace elements from the different contexts using mass spectrometry or IR spectroscopy.

Same story with most of the NA megafauna we've looked at. Migration is the exception, not the rule!
