Hi Lady N,
I will list all 12 children so that you can check that your 10 tally.
1. Your Thomas. I have 5 children born to him and Rebecca - Sarah (1838-1901), married John Layton & had 3 children, Thomas (1840-1917), unmarried, and worked most of his life at the forge at Mill Hill, William (born 1841) married Eliza Price & had 3 children, Mary Ann (1843-1928), married Thomas Dodd Grove and had 8 children, and Elizabeth Catherine (1845-1847). Which is your line of descent?
2. John (born 1806). Married Martha Fox. 6 children.
3. Mary Ann (1808-1855) Unmarried.
4. Charles (1810-1861). Married Elizabeth Jay. 7 children.
5. Sarah (1812- after 1891). Had George James (1829-1900) whilst unmarried. Later twice married but no further children. George is my ggggrandfather.
6. Elizabeth (1813-1893). Married John Wray. 6 children.
7. Susannah (1815-1901). Married Charles Phillips. 11 children.
