Indeed. Qrow mentioned them being born with silver eyes, while no one can be born with Maiden powers as they are received after the previous Maiden dies. Also, Maidens appear to be more like sorceresses that preserve the seasons, while Qrow described the silver-eyed people as warriors that strike fear into Grimm. It seems quite clear to me that the silver eyes are a completely different legend from the Maidens.
