I am trying to find information on Isabella Flintoff of Bolton UK (Born 1889? died 1972/3). She was one of 18 children. Her father originally came from Russia (Late 19th century) and when he arrived in the UK he anglisised his surname (not sure what from). Many of Isabellas brothers and sisters and other relatives emigrated to Buffalo, USA and Australia. She married John Oral Rigby and had two children, Estella and Alice.
I am trying to find out about her parents and siblings if possible.
