I remember my grandmother telling me that the Seabeck use to be something else, really hard to pronounce, that's why they changed it to Seabeck. Anyway, not sure if the same family, Grandmothers name is Pauline Seabeck, Great Grandmother's name: Mary Seabeck from Peoria, IL. If you have any more info I would appreciate it, if it is the same family I can get more info for you.
