I am part of the Australian O'Shannessy family. I am trying to research the family ofDenis Joseph O'Shannessy who came to Australia from Ireland in the late 1800's. I want to know who his siblings were, parents and other family members to make a family tree.Denis Joseph's children were Charles Denis (Bill), Colin, Morris (Mick Shannessy) and Netta. Charles Denis's children were Nada, Sylvia, William (Bill), Jack and Alice. Hope to hear from some relatives soon.
