A recent general analysis of light-baryon isospin splittings is updated and extended to charmed baryons. The measured [Sigma][sub [ital c]] and [Xi][sub [ital c]] splittings stand out as being difficult to understand in terms of two-body forces alone. We also discuss heavy-light mesons; though the framework here is necessarily less general, we nevertheless obtain some predictions that are not strongly model dependent.
