Hello NG
Thank you.
Looking for Michael's wife Elizabeth I thought I had checked all the deaths, including the GRO with ages for the 1850s deaths, obviously I hadn't, a senior moment of my own!
For young Mary I did have the GRO record copied, but the GRO record shows the age as 9 rather than 9 months. She was christened Mary Slater (living with Joseph Slater on 1861 census) with her mother showing as Elizabeth Allen (she married Martin Allen in 1852), and buried as Mary Ann Brady, with her mother recorded under her maiden name as a single woman!!
Again thanks
Glenn
