Robert, I think I can add a child to your family of Elijah and Hammah (Chambers) Dungan. On 21 June 1849 Joseph Totten married Frances Dungan in Shelby Co., MO. A year later the 1850 census has at Dwelling 600-622 the Joseph Totten family. Joseph was age 42 and b. VA. Frances his wife was age 33 and b. VA. All the children listed (7) belonged to Joseph and his first wife Mary A. Suitor. Joseph went to CA in 1851 and drowned in the Humboldt River on the way. Joseph and Frances had one child together, Joseph Wood Totten, b. 1850. On 10 Mar 1853 the widow Frances (Dungan/Totten) married James T. Cornelius and they had 3 children together: Sampson, Elizabeth and Tamar. Now here is the connection as I see it. In that 1850 census, with Frances at Dwelling 600, just 24 dwellings away was a family headed by Hannah Dungan, age 70. b. VA, and James Dungan, age 40, b. VA, Ann Dungan, age 37 and b. VA, and Saulda E. Dungan, age 6 and b. MO. Frances (Dungan) was age 33 (b. abt 1817) living just 24 dwellings from Hammah. From reading your posting, I assume that this Hannah of Shelby is the wife of Elijah Dungan.
Do you think this Frances is a dau. of Elijah and Hannah (Chambers) Dungan? It seems unusual to me for Hannah to have come to Shelby Co. and established a household if her husband died many years earlier in VA. Perhaps James is the real HOH here and Hannah just came to live with them. Any ideas? Are we sure that Elijah didn't come to Shelby too?
