Thanks so much, Roger.
I have the Australian Birth Cert of one of Ann's children. It states Ann Mcpherson was 34 yrs old in 1866, her maiden name was Power, her father was John Power, and she was born in Wicklow Ireland. This of coarse indicates she was born in 1832.
Ann Power's marriage to James Mcpherson was on 28/05/1850 at Portland Bay Vic Aus. Her age is stated as 21 years on the Marriage Certificate. This indicates she was born in 1829.
Ann Mcpherson's Death Cert 18/05/1872 lists her father as John Power, but there is something under it that I cannot read. I assume it is her Mother's name. Looks like Nil Stevenson. The Death Cert states Ann was born in Ireland and had been in Vic Aus for 20 years. It also states she was 17 yrs old when she married 'John' Mcpherson at Branxholme Vic. His name was actually James Mcpherson so there appears to be some errors on the Death Cert. Ann's Death was reported by a friend, not her estranged husband. The plaque at the Old Dunkeld Cemetery where Ann is buried names her as Sarah Ann Mcpherson, as does her son's Death Cert many yrs later. The date on the plaque correctly has Ann's death/burial date. It's evident that Sarah Ann ( nee Power) Mcpherson used the Christian name of Ann. I really want her to show up somewhere on Irish records, and sincerley appreciate your help. Frances.
