The Wynne family was originally Welsh and from Gwydir. They became a wealthy international Catholic family. 

The Wynne Sisters

• Parents:
  • Richard Wynne of Falkingham, Lincolnshire (of Welsh extraction)
  • Camille de Royer (French)
• Sisters:
  • Elizabeth (Betsey)
  • Mary
  • Eugenia
  • Harriet: her marriage
  • Justina.

Richard Wynne sold Falkingham in 1786 and toured the continent with his family. Betsy and Eugenia began keeping their diaries on the same day in 1789 in exercise books; Betsy was 10 and Eugenia 9. With the growing threat from Napoleon's army, they fled Florence on 23 June 1796 to Leghorn, seeking the protection of the English fleet. The Wynnes were evacuated in the Inconstant, whose captain was Thomas Fremantle. 

Betsy is famed for her diaries prepared for publication by Anne Fremantle in 1930s. The diaries begin on 17 August 1789 and end in 1820. Her sisters Eugenia and Harriet also kept diaries.
