Michael, Hello from Liverpool and an extended family of Achilles's descended from Augustine Halpin Achilles of Ireland in the 1700's who ended up in Liverpool by the late 1880's. My cousin peter has researched our family tree if you would like us to post you a copy (not all of us have PC's!) We also think there is a German connection? and an Italian one?
My dad was from a family of five brothers/one sister, my grandad from 3 brothers. See if any of our descendants names ring any bells, they were: Augustine, Frederick, John, Thomas - repeated over several generations (my dad & brother being the most recent Thomas's)
We would be interested in knowing about any other Achilles's out there?
