I am new at this, but in some of my research on my part of the Jones family, I see a William Daniel (maj. gen R.A.) married Elizabeth Smith, daughter of George Smith, Esq. of Nottingham in 1828. He died in 1853, having issue (but not listed). Hopefully this will lead you on a new journey. Good luck, and perhaps you can help me down the line, when I get to the Wales people seriously. I'm still looking in Iowa and the States!
