I cannot find a Death Cert. for Mary Ann Bambrough Born 1846 in Greenock Renfrewshire and Died between 1901 and 1911 in Newcastle upon Tyne possibly Byker. I paid £60 recently for 3 hours Research and Researcher could not find Mary Ann's Death. Last definite time she was alive was December 1899 as Informant on her Son's Death Cert.Son's Name Richard Raine Bambrough,22 yrs old when he Died. I found a Mary Ann Bambrough in 1901 Census who stated she was a Widow aged 56 Born in Scotland and a Servant in a Family named Hall in Byker. I believe this to be her. Mary Ann was a Widow when she ReMarried John Bambrough in 1875. I know everything about Mary Ann (my Gt Gt Grandma) except her Death Date. She is on 1881 Census with lots of mistakes.Stated as Daughter of John instead of Wife and his Daughter Margaret is down as his Wife and  their ages are transposed too. I have been doing Family Research for over 20 years but this has got me beat. Has anyone any suggestions?
