Thank you both for your replies and suggestions.
According to familysearch she married (John Hastings) on 8 Jun 1830
All saints, Maidstone. They lived and had children in Leicester and in Nottingham.
Her eldest daughter was Sarah Ann Valence Hastings born 8 Sep 1825
Workhouse, Nottingham. Who knows whether the father was JH?
I took her maiden name from the birth cert of her son and my gggrandfather Elisha (Hastings) born 13 January, 1838 in Leicestershire.
I'll explore the 24 Lt. Dragoons, thank you for that.
