I am currently researching both Humphrey Jones born 1815 and his wife Sarah Jones born 1820 in Llangollen, Denbighshire. Some of their children were Elizabeth Jane Jones born 1848, John Jones born 1841, Thomas Jones born 1836. All of their children were born in the United States in Iowa.
If anyone has any information either about them or their parents please let me know. So far I have not had much luck in my searches.
