Find Ancestors

I am trying to find all descendants of William Downing Evans, who was a Welsh poet and who lived at Woolaston House in Stow Park Newport. He was born in 1811 and died in 1897. The child by his first wife Louisa was: Hilda b.1843 Newport Mon and married in 1880 to Thomas Richards. She only had two children with him I think and he already had a few children from a previous marriage. Thomas Nicholas b.1854 in Ipswich Don't know if he married? Louisa Caroline b.1856 Newport Mon. Married Thomas Henry Hazell in 1881 and had children called Henry, Ethel and Sara. Louisa died at Woolaston House in 1888. Catharine Mabel b.1858 Newport Mon and died in 1880 at Woolaston House Adah Downing 1861was my Great Great Grandmother and I know all about her Elizabeth Mary b.1864 Newport Mon. She married George Talbot Woolley ( my 4 x Great Uncle) in 1883. They moved to Oz in around 1886 and had three children. She died in 1890 in Australia. Eleanor Girlin b.1866 Newport Mon. She married Alfred Hewertson Stone in 1899. I don't know if they had any children. I would love to hear from anyone who is descended from the children, apart from Adah as I know all about her family. There must be some children out there who are the same age or thereabouts to me and who remember there grandparents etc talking about William Downing Evans. I'm trying to complete that side of my family tree and would really like to fill in the blanks. If anyone knows who his first wife was then that would be useful as well.
