Hiya David

In 1841, she was in Liverpool with her family. Her age then is stated as 40. The spelling of Deborah not surprisingly varies. In 1841 & 1861, it is Debra. In IGI, her marriage record from 1826 in Liverpool shows Deborah. There is no doubt that that was her name. The family seems to be absent from the 1851 census of England & Wales. She died as Deborah Cassidy in April 1862 in Liverpool. Her age is stated as 70 on the death certificate, but she had a son Michael born in 1837, meaning she would then have been 45, which seems unlikely.

Thanks for taking an interest.
