I am researching my father's family (TOSSICK). I've run across information that indicates that the family name was originally DVORAK, but my direct line apparently split from the family taking the TOSSICK name. It's also possible that TOSSICK was the original name and was changed to DVORAK, and my part of the family reverted to TOSSICK. Does any DVORAK family have any information concerning a split of family in the late 1800's to early 1900's? My great-grandfather used the name JOHN M. TOSSICK in 1900, but his son, my grandfather was baptized EDWARDUM FRANCIS DVORAK, b. 27 Jan 1886, and great-grandfather was called JOHNANNE DVORAK (and married to BARBARA SEDLAK (or SILACK).
