I found a link to John's tombstone at the FindAGrave website. This also gives a transcription of his obituary from the Democrat-Argus of Caruthersville, Missouri of Friday, December 1, 1944. Transcription states his birthdate was February 15, 1869 at Savannah, Tennessee. This may be a typo, as other records place his birth as closer to 1862, such as the 1870 census of Colbert County, Alabama. His death certificate is online through the Missouri Secretary of State website:
At first I wasn't sure who the informant, Robert TREECE was, but now thanks to the FindAGrave transcription of the obituary, I know that he was a son-in-law.
John married Dollie BRUMLEY on September 22, 1904 in Hardin County, Tennessee. She was his second wife. According to the obituary, they had four sons and three daughters. I found record of their marriage at FamilySearch.
His obituary states that he married his first wife, Martha Adaline PACE, in April 1877. I found a record on Ancestry.com that may be this marriage record. This would be taking place in Prentiss County, Mississippi.
John had a total of 15 children by his two wives, according to his obituary.
I still have a lot of research to flesh out these families, but now I have leads for more of Eileen's distant cousins throughout Alabama and Tennessee.
