Jack (b 1922) and Greg (b 1929) were 2 of the 7 children of John Francis (Jack) Carrucan and Margaret Ellen (Maggie) Doherty who lived at Cheswick in country Victoria. This photo, taken around 1943, shows Jack, then aged 21, in military garb. Greg, born 1929, would only have been around 14 at this time.
Jack and Greg are great grandsons of Patrick Carrucan who migrated from Co. Clare to Eltham
