Hennessey families of Warwick

I am looking for any descendant of James Carroll Hennessey and Matilda Loy (nee) Hennessey, or Francis Antoine Carroll Hennessey of Warwick, a son. James Carroll Hennessey conducted a cooperage at Miclere and subsequently on the Nebo Road. James Hennessey died at 87 years of age on February 4, 1836 at the District Hospital in Mackay, Queensland. He was survived by Mrs Hynes, Mrs McGrath of Esk, and Mrs R Francey of Mackay,  John P Hennessey of Melbourne, James G Hennessey of Sydney, H W Hennessey of Mackay, A J and W H Hennessey of Brisbane, and Francis Antoine Carroll Hennessey of Warwick. During the American Civil War, James Hennessey served in the Union Army. A memorial is being compiled for him and family information is needed to complete his story. Anyone with information is asked to contact James M Gray, Cmdr, SCV Camp 2160 in Brisbane.
