Hi everyone, the certificate came through today and its proved to be very positive.
The certificate lists Julia as wife of Thomas Logan, a Tailor. She died of Dropsy and Exhaustion aged 51 at 8 Wolstenholme Buildings, Heywood and the witness it Thomas Entwistle - a confirmed direct link to me.
Thank you all for your help this is really great stuff : )
Do you think I should go for Jonw65's suggestion - 'There's a death of another Thomas in 1870
June 1870 Manchester 8d 194, Logan, Thomas, age 44' e3ven though it says wife rather than widow on Julia's death certificate?
