Michael Ryan b1836/Julia Hogan b1842 Roscrea

Looking for information on the forebears of Michael Ryan and Julia Hogan both emigrated to Canterbury NZ area on the “David G Fleming” arriving Lyttleton 13 Dec 1863.They were married Christchurch 1864.

Michaels Obituary states they were from Roscrea and his date of birth was11 October 1836. It mentions he worked on his father's farm as a farm labour before his departure. His death certificate lists his father as Michael Ryan? no mother listed.

Julia was born 1842, no parents are listed but father's profession was farmer on her death certificate.

Any information would be appreciated.

Cheers

Brent
