Yes, Richard Pease was the son of William Pease and Hannah Whitehead.
He died at the Union Workhouse, Brackley on 11 March 1857 and was burried at Westbury on 14 March 1857.
Mary, his wife, died on 17 May 1854 of "Visitation on God" aged 84 years.
I understand that Visitation of God was used to explain an unknown cause of death, so it is reasonable to assume she was a healty 84 year old.
Thank you for taking the trouble to check for me.
