I hope the following notes help you. These are based on notes made following research on the Clyro Court records held at Powys Archives, parish records, and newspaper reports, whilst researching a Thomas Baskerville Mynors Baskerville .
The will of Herbert Beavan, the Elder, of Clyro, Radnorshire, was proved at Brecon, in 1800, in which he left everything to his eldest son Herbert Beavan, the Younger, other than a rental income to his second son William Beavan.
Herbert Beavan the Younger of Clyro, married in 1814 at Llandewy, Radnorshire, to Ann Jones, daughter of Thomas Jones, of Gogie, Llowes. By deed of settlement dated 1st December 1813 he settled property , Lower House, Clyro, on his future wife.
Herbert Beavan, the Younger, of Lower House, died in 1822, and was buried at Clyro on 21st May, aged 70. The executors of his will were his widow Ann and Thomas Higgins attorney. He left everything to his wife, but the subsequent legal disputes hinged on whether he included the settled property, Lower Court
Ann, the widow of Herbert Beavan, the Younger, married Joseph Lewis in 1830. Joseph Lewis died 18th November 1850 at Lower House, Clyro, aged 42. She died intestate 1859, aged 74, in the Briton Ferry Asylum.
If these ages are correct then:
Marriage in 1814 Herbert Beavan (aged c62) Ann Jones (aged c29)
Marriage in 1830 Joseph Lewis (aged c22) Ann Beavan nee Jones (aged c45)
When Herbert Beavan, the Younger, died in 1822, he had no children, and although his wife inherited most of his assets, if the settled property was not included then on her subsequent death in 1859 this property would pass to his heir, or his successors.
Although William Beavan, the brother of Herbert Beavan, the Younger, was living at and farming Woodseaves, Eardisley, Herefordshire, the legal owner of this property would have been Herbert Beavan, the Younger, until 1822, when his widow Ann inherited it. On her death in 1859 ownership would have passed to her legal heirs.
The brother, William Beavan, of Clyro had married on 3rd August 1782 at Clifford, Herefordshire, to Ann Higgins of Clifford.
Their eldest son, Thomas Beavan, was christened at Eardisley, Herefordshire on 13th February 1787.
On the death of William Beavan, of Woodseaves, his rights passed to his eldest son Thomas Beavan.
Thomas Beavan married Priscilla Williams, both of Clifford, at Clifford, Herefordshire on 14th February 1807.
Their eldest surviving son, Herbert William Beavan, was christened at Eardisley on 5th August 1815.
Thomas Beavan of Woodeaves, aged 49, died 16th July 1839 (buried at Clifford)
Following the death of Ann Lewis in 1859 administration of her estate was granted in 1861 to her sister Meliora Llewellin, of Hay, Herefordshire, the wife of John Llewellin, timber merchant, being one of her Next of Kin.
I suspect that Meliora Llewellin and other family members had taken legal action to eject Priscilla Beavan and her family from Woodseaves (it being legally owned by Ann Lewis, who may well have been in the Asylum by then) hence its seizure and disposal by the Sheriff.
The case of Llewellin v Probert (The Probert refers Lewis Probert of Ledbury, Herefordshire ) in 1860s concerned the original settled property Lower House, Clyro, which had been occupied by Ann Lewis, and if it was owned by her Llewellin heirs or by Herbert William Beavan, the son of Priscilla Beavan nee Williams. The courts found in favour of the Llewellin family.
It is a pity that the courts did not find that Herbert William Beavan was the legal owner as on his death in 1867 at Witney his rights may have passed to his daughter Catherine Fortune Wanklyn nee Beavan. HWB had abandoned Fortune (and his wife Catherine) in 1851 leaving them in Hay workhouse.!
