Mary Emily (Pott) was born in Bloomsbury, the daughter of Charles and Anna Pott. She was baptised in St George, Bloomsbury.
In 1841, Charles and Anna were living in Bromley with their five children.
They had a country house in Bromley, since the 1820s, when Charles Pott had leased Freelands, in the Plaistow district of Bromley, from local landowner Sir Samuel Scott.
Charles Pott and Anna ran a fairly lavish household - they employed butler, footman, groom, cook, lady's maid, two housemaids, kitchen maid, one nurse and there was also one nurse specifically to wait on the children. Charles Pott was a wealthy man. When he died in 1864, his personal effects alone were worth about £70,000 (contemporary values).

Charles Pott was a Governor of the Foundling Hospital (1817), Treasurer (1839 to 1852), and Vice-President (1856 to 1864). He was the son-in-law of Samuel Compton Cox, who was Vice-President and Treasurer, and a vinegar manufacturer in Southwark. He resigned in 1852 owing to a misunderstanding with the Committee. He and his wife were buried beneath the Chapel.
A Foundling Museum opened on the site in 2004, which covers its history over the almost 200 years and 25,000 children it cared for.
