In the case of the specific examples you gave: Megan - correct diminuative of Margaret, the rest are variants Alison - correct diminuative of Alice, the rest are variants Caitlin - correct Anglicization of Caitlín, rest are variants and I would argue that Katelyn is a different name entirely-- combo of Kate and Lynn Catherine - French form of Katherine and common English variant Katherine - original form Sean - Anglicization that's the closest to the original Seán, but the other two are also common Anglicizations
