To all Listers Whilst going through the 1851 Census index for Lambeth London /Church District , for Cathy Cliffe. I came accross an entry as follows. Lambeth Work House Ann Knibbs Aged 44 Occupation Charwoman listed as inmate Pauper. I cannot find an entry of her birth so assume she married into the family. Hope this is of some use. PS. (Don I wondered if this could be the unknown Ann who married Francis Knibbs in the London area ? ) Regards Bob Knibbs
