Hi Daryl. Welcome to WikiTree!
The profile for Australian bush ranger Frederick Wordsworth Ward is at this link:
https://www.wikitree.com/wiki/Ward-6158
If you keep adding profiles of your ancestors to WikiTree, following the start you've made with your parents, then sooner or later you will make a connection to profiles that already exist. There is a chance that a relationship to Frederick and his wife Mary Ann will then be revealed.
