Finally opened your post dated January 11, 2003.I have been able to get some information for you through my own genealogy searches:
My Grandfather, Ernest Chalmers Ronk was the son of Henry S. Ronk according to his death certificate.There was no information listed for Thapena Ronk.Ernest Ronk was born in Canton, IL (Fulton Co.) on 09-11-1877.(9-11) how scary!!He later married Eva Mary (Mann) Ronk.They had three boys, Raymond, Eugene & Earl. Earl Leslie Ronk was born 07-17-1907.Earl Ronk married Elaine Margaret (Gustafson) Ronk.I am the sixth child of Earl & Elaine Ronk.
If you or Angel Bates has any information about Thapena Ronk it would be greatly appreciated.
If you can shed anymore light on George W. Ronk and/or Sara Jane (Cary) Ronk I would like to continue my research in the family past.
