This information relates to a currently unidentified main branch of the family with roots in Lincolnshire.
Yesterday at Bletchley Park I met David Barton, who is researching the Braddon One-Name Study. Today David kindly gave me some information on Susannah Pask from the Grantham Petty Sessions dated 15 January 1847:
Jas FURMIDGE, of Sedgebrook, consented to pay 1s 3d in an affiliation case: the Magistrates allowed the small sum in consequence of the female (Susanna Pask) having previously had a child.
The report referred to Susannah, the daughter of William & Ann Pask née Whitehead.
The information came originally from Anne Cole, who has been collecting reports from the Petty Sessions bastardy cases reported in the Lincoln, Rutland & Stamford Mercury. Her transcriptions for 1847 are available in Genuki.
