I have NO idea of birth and death dates of James at this time. I only have a name. I estimate that he would be 20 - 30 years of age when his son John Duggan was born in 1853 in same locale but died in Australia. This is early research and will update as i find more information.
Listed as parent on death certificate record of John Duggan (death certificate 1566/1931) https://my.rio.bdm.vic.gov.au/
