My Great-great grandfather was Daniel SULLIVAN of County Wexford, Ireland. He married Mary Hogue or Hogan of EBR Parish and I'm descended from their daughter Mary, who married Jesse Edwards.
This is the SULLIVAN family that SULLIVAN Road in Central is named for. Daniel's siblings who emigrated separately from Wexford were Mary Finlen/Fenlon, Patrick (m. Mercy Jackson), Michael (we had a crash and I don't have his wives loaded right now - ha ha), and James. Michael lived in Livingston Parish.
I am very anxious to place these folks in Ireland, but lemme tell ya, Daniel, Patrick and Michael Sullivan are not the easiest names to research!
