I am seeking confirmation of the birth c 1858 of Sarah Borthistle in Co Wexford IRE. She migrated aged 7 with her family, arriving in Melbourne Dec 1865 on the Donald McCay. Parents were Thomas Borthistle and Jane Borthistle(nee Donovan) from Parish of Ferns,townland of Effernogue. Sarah married James Kennedy at Enmore Sydney in 1883 and birthplace was listed as Wexford on the marriage certificate. I know that civil registration in Ireland did not start until 1864 but I am hoping there may be evidence of Sarah's birth details.
