Mid North Coast Pioneers - Newcastle to Lismore and beyond

A search of the NSW Birth Index revealed the following entry:-

10120/1858 JONES ELLEN JOHN ANN NEWCASTLEAs this birth year is one year after her husbands, there is a strong likelihood that this may be her entry.This is likely to be correct entry as it is stated in her daughters birth certificate that Ellen was born in Burwood. Burwood was the early name for Merewether. There is also another entry:- 8994/1858 JONES ELLEN E SUSAN L MAITLAND There is no record of an Ellen Jones being born in 1857 or 1859.

Or a copy of this certificate: 10695/1857 JONES SARAH E WILLIAM CATHERINE RAYMOND TERRACE.I need to establish whether her name is simply Ellen or it is Sarah Ellen. Sarah Ellen is mentioned in the NSW Death Index. This links her as her surname is WILSON. It may be that John and Ann have been incorrectly entered as her parents and that it should be William and Catherine.
