We know of Hannah from the following sources of information:
1. Burke's Peerage gives an overview of the Caldwell family and the Crompton family. Under the Caldwell section, it states that Elizabeth Caldwell's parents were Thomas Stamford and Hannah Stamford (nee Crompton). Hannah's father was a John Crompton of Chorley Hall, Lancaster, which property was aquired by that branch of the family soon after the rebellion in 1715. Hannah was a decendent of the Rev John Crompton MA born in 1641 and cousin of Samuel Crompton of Derby, Esq, and a cousin of Henry Cope of Duffield, Esq,: a share of whose personel estate came to Hannah's daughter Elizabeth Caldwell (nee Stamford).
2. Information supplied to me by Sheila Howells who has researched this from many sources including the Crompton Papers in the Derby Local History Library.
3. An Almanack from 1747 owned by Hannah and listing many of her relatives and acquaintances.
