William HERRING  - Am researching my late husbands forebears, and have learned he is connected to Tyson family through his g. g. grandmother Barbara Tyson daughter of William and Isabella (Coulson) Tyson. Barbara married Wm. Diogenes Herring at St. Peter's Campbelltown in 1838.   He was a convict and I have much to learn about him and the Tyson family.  My search for Wm Diogenes Herring is not helped by the fact that there was another convict Diogenes Herring.  There are too many death registrations for William so need to find him some other way, before I have lookups done. The marriage entry at St. Peter's gave no age or parents names. Wm. Diogenes was 26 when he arrived in Australia in 1834. Diogenes Herring was 17 when he arrived in 1829.  Which one belongs to my husband's tree?   Is anyone else researching this family?
