I may possibly have some information for you--at least a clue to follow up on. John B. Pass (who was born in Georgia) and his wife Elizabeth Ewing Pass (who was born in Alabama) moved to Grenada MS in 1832. I have a list of 5 of their children from the 1850 census, but it doesn't include a Celia. However, I have another reference ("Biographical and Historical Memoirs of Mississippi") that said that they had a total of 8 children, so Celia, Archie and Caledonia could have been their three youngest (Archie and Caledonia at least were born after 1850).
