The information that I have verified is:
My Father was Cecil Peel Beresford Mathews 1931-1991
Grandfather Alfred Henry (born in Antrim) 1897-1951
Greatgrandfather Marcus Beresford 1862-1947
Great-great-grandfather Frederick Albert 1827-?
Great-great-great-grandfather Rev. Robert Mathews 1798-?
It is documented in Father Theobald's biography that Lady Ellisha (who paid for his education) had promised to cover all his debts on her death - however this didn't happen had he had a terrible time trying to pay them off, as he head spent freely on the promise of his inheritance.
"This old lady, who by all accounts was at least as fit for a lunatic asylum as her brother George" (London Times 06/09/1843, left everything to Viscount de Chabot against the express wishes of her brother Francis James 2nd Earl of Llandaff (died 1833), who had left the estate to her. She died 14/12/1841 in her house in Molesworth Street, Dublin.
The family over the years changed their religion to suit the times and to hold onto their title and estates, as was the way in Ireland in those days.
It is good to have found you again Christine.
I just can't seem to fine a link between Robert and Elisha (Elizabeth).
I hope somebody can help.
