This could be the John Brosius I am looking for even though our dates do not correspond. I know Lydia is buried at St. James Cemetery, Ringgold, Jefferson Co. Tombstone reading "Lyddia Powell, w/o Elias, died 1865, age 66 years". Elias Powell was 2nd husband of Lydia/Lyddia. Lydia's parents: Daniel Haas and Rosina Mattern. This would have made Lydia's birthdate 1799. Dates on John Brosius: 1797-1836 are from a book called The Mattern History by Avice Morgan. At this time I don't know her source. I know John's date of death is correct due to an obituary I have on his oldest son, Isaac. I am most interested in knowing what you have on this family. I will post Isaac's obituary in separate posing under his name.
