Charles Henry Delaney is my mother in law's grandfather. I have also been researching your branch of the family. In my research I have John married to a Sarah Katen - they were married 1861 (this can be found in the NSW BDM).
About 15 years ago I made a phone call to an Olga Poole(y) - was she related to you?
I won't be putting all my Delaney tree on Geni - but if you are interested we can compare notes via email.
