One of my great great grandmothers Sarah Susannah Roberts is in all the English census from 1841 when as a 6 year old girl, she is living with her parents in St Breward, Cornwall, to1911 when as Sarah Susannah Philp she is living in Penzance, Cornwall with one of her daughters and her family, this time aged 74.
In between times she was married to Robert Crowl or Crowle, and her eldest daughter, Elizabeth Hannah Crowl emigrated to Australia with her husband Richard Marshall and that's where my grandfather was born.
