Families in Australia come from 3 trees.
The majority of those using the Hayde name are descendants of Tree # 1 who settled initially in New Zealand and then in more recent years some have migrated to Australia.
The second tree relates to a family that adopted the Hade surname and are linked to Tree # 16 and are descended from Matthew (b 1818) who was sent to Australia for being a pick pocket in Dublin.
The third tree links to a family that emigrated from Germany and uses the Hayde name. This is Tree # 13. This is covered further at the German posts page.
