Marion Waddell Chapman was born on 15^th November 1846, the second child of Mungo Chapman and Elizabeth Waddell to bear that forename, and the eldest of those who survived into adulthood.

Marion was aged 4 at the time of the 1851 census; a scholar aged 14 in 1861 and 23, unmarried, in 1871, on each occasion living in the family home. Marion Chapman was one of two witnesses to the marriage of her sister Elizabeth Chapman and Peter Stuart Brown in 1870.

She was still surviving in 1879 and mentioned in their father’s Trust Disposition and Settlement, as ‘Marion Chapman or Thomson wife of Thomas Thomson Merchant Susanne (sic, this should be ‘Lausanne’) Road Peckham London’.

According to Internet sources, Marion Chapman married Thomas Thomson on 27^th July 1873, at St. Paul, Deptford, Kent; as noticed by the Falkirk Herald, 23^th August 1873.

Marion and Thomas had at least two children, Lizzie Thomson, baptised 27^th Aug 1876, and Andrew James Thomson, 26^th August 1877, both at Camberwell, Surrey.

Thomas Thomson acted as informant on the 1902 death certificate of his mother-in-law, Elizabeth Chapman MS Waddell. According to family lore, Marion was subsequently widowed and shared a flat in Edinburgh with her sister Elizabeth, also a widow, and died in Edinburgh c. 1919, but these particulars are yet to be substantiated; it is possible that there is an element of confusion here.
