No, it's quite obvious that Jude took the Heartfilia name. He would have done it to preserve the name of the prestigious clan. Also, Anna's name is only Heartfilia so we can make an easier connection between her, Lucy and Layla, rather than, "Oh this is your ancestor, Anna ________, but I promise you're related even though you're a Heartfilia."
