Hi Nick
Paddy Montgomery’s original name was Patrick Cannon. He adopted the name “Montgomery” for professional circus purposes. He married Katie Shand, daughter of Ernie Shand (original name McMurtrie), both famous circus riders. All of these people were particularly active in the 1890s/early 1900s, especially in FitzgGerald Bros Curcus, at the time Australia’s leading circus.
Paddy and Katie had two children, Ron Shand and Iris Shand, both vaudeville and “legitimate” stage actors. I met and interview both Ron and Iris many years ago. You will find transctipts of these interviews and other interviews in the National Library of Australia. Ron Shand was one of the leading characters in the 1970s TV series “No. 96”.
I have prepared a bit of a family tree which you will find on ancestry.com:

Hope this helps a bit. Let me know if you have any further queries.
