Hello Frank: I did some more work on the Thackeray family last night. I have the following children born to Thomas and Jane (Fisher) Thackeray.
1.Edwardborn ca. 1824Thearne married Ann Baxter 1851 2. Thomasborn ca. 1831Woodmansey married Mary Ann Maddison 1850 3. Annborn ca. 1828married Robert Suddaby. 4. Williamborn 1835died 1841 5. thomasborn 1825died1825
I found the census information from the 1841 census and Jane is listed as a widow by then so looks like Thomas has died before the census record:
1841 census: Woodmansey

Also found on that census a family of Edward Thackeray a couple of doors down.
