I am relatively new to the genealogical scene, but I have become quite fascinated with searching and finding out bits of information regarding my past. I am, however, stuck on a few key people. Here are the major points with specific reference to (what I believe is) my line:

James J. Sweatman (1754-1823)
(m) Mary ???
1a. Augustus Sweatman (1800-1986)
1b. Edward Sweatman (b. 1805)
(m) Ann ???
2a. Mary Sweatman (b. 1832)
2b. James Sweatman (b. 1836)
2c. Samuel Sweatman (b. 1840)
2d. Daniel Sweatman (b. 1842)
2e. Rebecca Sweatman (b. 1847)
2f. Amanda Sweatman (b. 1849)
2g. Dennis Sweatman (b. 1850)
(m) Jane Sweat (1845-1918)
3a. Barney Edward Sweatman (1875-1969)
3b. Emma Sweatman (b. 1877)
3c. Rufus Wesley Sweatman (1877-1960)
3d. Annette Sweatman (1878-1956)
3e. John Sweatman (b. 1879)
3f. Eli Washington Sweatman (1884-1966)
(m) Jennie Wells (1889-1962)
4a. Carl Alden Sweatman (1911-1970)
4b. Eli Washington Sweatman, Jr (1915-1996)
(m) Marguerite Case (1918-2004)
5a. Jennie Sweatman
5b. Eli Washington Sweatman, III (1949-2008)
1c. Stephen Amos Sweatman (1805-1864)

My father was Eli Washington Sweatman, III. My sticking points are related to several things: 1) where does the line go after (or in this case, before) James; 2) what can be known about the line of Jane Sweat; 3) what can be known about the line of Jennie Wells; 4) what can be known about the Case line; and 5) more generally: is this information correct?
