Hi,
Your Charlotte Louisa Lacy was born in the last quarter of 1856 at Clay Hall in Alverstoke. She had a brother, James born 1857 who was my great-great-grandfather.
Their father was James John Lacy, born 24 Nov 1804 in Plumstead, Kent and his father was Major-General Richard John James Lacy (photo of early portrait enclosed).
