Eleanor born about 1819, died 1887 Wagga Wagga. Married Patrick Fennell. Have a list of their children and some descendants with some headstone photographs, but not much else.
Thomas, 1813 - possibly 1894- I believe he married a Mary Veale Glanville. Seeking more information.

Ann, 1816. This is all I have. Seeking more information
Cornelius - 1820 - 1823. Can anyone clarify this one?
