Her father died in 1838 and on 1 November of that year her mother married Humphrey Smith, a widower.
She married Robert Pearce Yardley an ironmonger of Chorlton-on-Medlock on 2 May 1857 and they lived at 19 Darlington Street, Cheetham Hill, Manchester.
However, Robert died, aged 37, on 16 November 1860 leaving his wife as sole executor of the business.
The 1861 Census returns for Duke Street shows Emily Sophia living there once again with her (by then twice widowed) mother.
After 1881, the L&YR entered into an exclusive contract with the Railway Signal Co. and orders to Smith and Yardley dried up.
