The only census that I believe I was able to find and that is the 1850 Census Lowndes County, Ms.
Catherine F. Sullivan -age 49 -white female Born South Carolina. --------Maria Sulivan -age 26 - B/P South Carolina,- Elizabeth Sulivan age 19 - Georgia, - Eliza Sulivan -age 17, -Georgia, - John Sulivan - age 13, -Mississippi, - James Sulivan - age 11 - Mississippi.
I have 2 conflicting dates of death for William Sullivan, one is 1850 and the other one is 1862. I don't know which is correct. I found William Sulivan in a 1830 Census for Monroe County,Miss. But he was the only one listed.
Catherine has a few brothers and sisters, and if you need those just let me know. I can do some research in Mississippi I mean go to the books to find them in Monroe Co. That may be the only way that you can find out information. Thanks for letting me work on this. Nancy
