Very interesting! I have been trying to figure out the murdered Dungan for a long time.
I have a notes indicating a family legend of a Judson or William DUNGAN murdered by his son-in-law during a robbery with a note that this may be William M. DUNGAN m. to Martha Jane WALTERS. Also that this may be William the son of John DUNGAN m. Sarah Jane WOODS, brother to a Judson DUNGAN whose descendents say he definitely was not murdered. Then in a separate note I have
William “Durg” b.bef 1876, d.Jan 22/28, resided Rocky Springs, murdered CH: 9Edd Dudley b.4/28/1896, resided Utica MS CH: Hyrum Earl b.7/30/1928
Maybe if we dig a little we can document if these are the same person and if one is your William. If so, I have the lineage way, way back for you. Let's start with anything you can tell me about who they married and any other children you may have listed for each generation. Feel free to post here or to contact me at firstname.lastname@example.org. Thanks.
