Birth of Ann Croucher in FreeBMD in July-September 1845 in Cuckfield (7 320).
In the 1851 census as Ann Croucher aged 5, born in West Hoathly, Sussex, and living with her widowed mother (Elizabeth), brother (William) and sister (Martha) at Sidny Cottage, Staplefield Common, Cuckfield, Sussex.
I cannot find any later information - she was not with her mother in the 1861 census.
