Hello all,
It looks to me like the age at death for Constance, at 26 years is a grief stricken fathers mistake at the shock of his only childs death. All the other evidence points to a birth 1888/89.
Her parents Edwin Landeer John Steell, married Eliza Levy Sanbach, 1886. Skirling, Peebles.
There is also a death for her mother Eliza Levy Sanbach/ Steell, 1942. age 83 years, Newington, Edinburgh.
Regards,
Jonn.
