I notice that there is no death date on Line 23b for Jane Cree.  She died on 26 September 1918 and is buried in the same grave as her husband George (1851-1932) and her son Arthur (1891-1914) in Belfast City Cemetery - Grave No J1 167.

Jane's age at death was given as 65 which would give her a birth date around 1853.

Their last address is given as Suffolk, Dunmurry, Belfast.
