I have now found my G.G.Grandmother who was Sarah Ann Vearonelly. She married William Joseph Abbott on 14th Aug 1853 in Stepney, London. She was then aged 22, so would have been born around 1831. Her father is named as John Vearonelly. I appreciate the spelling isn't the same, but experiance is telling me that names were spelt phonetically in some cases. If anyone has any further info, please contact me.
