My Thomas Llewellyn married Mary _____ of Aberdare, Glamorgan. Children: Thomas (b.c.1832, Wales), John W. (b. 1836, Aberdare), Gwenllian (b.c.1840, Wales),Lewis (b.c. 1843, Wales), David (b.c. 1846, Wales), Edward (b.c. 1849, Wales) and Margaret (b.c. 1850, Wales). John W. Llewellyn is my g-g-grandfather. He died Nov. 4, 1874 and is buried at Welsh Hill Cemetery in Mineral Ridge, OH. John W. came to the U.S. July 19, 1862 on the steamship Constellation to New York. What else did the Obit say? Mother & father? When John was 14, his family lived on Bute St. in Merthyr Tydfil. Check the 1851 Wales Census (HO 107/2460). If this David arrived in 1854, he would have been about 8 yrs. old, which means he came with family. John would have been 18, maybe he stayed and came later. I don't know. Let me know what you find.
