Hi Jane- As we are dealing with some very common first and last names, the chances are slim that we are connected, but here goes. Richard Hughes, born in North Wales (approx 1845), came to America (date unknown) and settled in Ohio. The 1880 census has him living in Madison, Jackson County, with his wife, Mary, their son Joseph, and Mary's mother, Mary Thomas. I have Mary Senior's birth as about 1810 in Wales (town unknown). I do not know her maiden name. Mary Thomas, Junior was born about 1846 in Ohio, exact location unknown. This is all I have on the Thomas family. I don't suppose any of it is familiar? -Rachel
