Hi Rachel,
Bit of a tangent but I am sure Watkin Williams-Wynn is the illegitimate father of my great-grandfather, George Rogers. His mother was Mary who worked for the family of the estate at Llangedwyn. After George was born in 1870 he is listed as the child of Thomas and Ann Rogers (nee Vaughn) who were Mary's parents and also worked on the estate. Curiously Mary disappears from the estate in the 1881 census and Thomas and Ann have moved from a relative hovel of a cottage to the gatehouse of the estate with George who is now nearly 10 and is listed as their grandson. By the 1891 census George has disappeared from the estate as well. He became a railway signalman and worked on the Wirral until his death in 1932 from Tuberculosis. Ann died at Llangedwyn in 1889 aged 66. Thomas died at Llangedwyn in 1895 aged 85. Both are buried together in the churchyard of Llangedwyn with a splendid headstone which I presume was paid for by the Williams-Wynn family. Thomas and Ann also had their own pew in the church.
I was curious about your potential link to the estate through your family and wondered if it was just a theory or you had some other evidence? I would love to help out if I could, let me know any other details or ask me for any other information you may want.
I have built my theory up over quite some time and I was going to ask the current Baronet if they would participate in a DNA test with myself but I haven't got the courage up yet and I'm not sure what it will prove! Thomas and Ann were Welsh speakers as was my great-grandfather and his eldest daughter and eldest son, Thomas Maldwyn Rogers, who was my grand-father. Thomas Maldwyn regularly visited relatives in the Wrexham and Johnstown areas in the 1940's and 1950's and took my dad (born 1936) with him. My dad remembers they used to go for goslings which were brought home to be fattened up and sold at Christmas time.
Best wishes, Steve Rogers.
