Hi Kris,
Thanks for looking. All the info I have is post 1851. On the 1861 census she is shown as Emma Sims ,married to William with three daughters, the eldest two, Emily and Elizabeth have their surname recorded as Parker. They were born in 1853 and 1855 in Warminster. The third daughter, Sarah born in 1858, also in Warminster, is my wife's Great Great grandmother, hence the interest.
I am assuming Parker is Emma's married name because of her two daughters carrying that name.
That's all I have.
