She was married to Henry Carrington.
She had up to eight children (you just don't know if there may or may not have been a previous wife!)
By 1901 the census lists her as Widowed and living at 16 Kensington Road (or House?) in Lakenham, Norwich. Her son Henry was living at number 11, and her married daughter Eliza at number 12. Her future daughter in law (also called Phoebe) lived in Lakenham, although her son James at this time was living in Blackburn, with his first wife.
The only match I can find for her in the 1851 census is a Phoebe Smith living in Mill Street, Lakenham, Norwich. Her parents were John and Elizabeth Smith. He was a gardener, and she came from Wymondham.
