Thank you TerryB and east tennessee roots! Very kind of you both to take a look.
Yes, TerryB, I was surprised that the Online Obituary Index from the Daviess County Library had it listed as, "soldier - Civil War, CSA, drummer, Co. G, First KY Cavlary," in its index to an 1890 newspaper article. It could be a mistake in the index, as I've never heard of drummers in the cavalry! I did get copies of all the newspaper articles, however, I'll have to double check the original article.
As far as I know, east tennessee roots, Frank was just Frank Wecker or Wicker. He had a son John Frank so maybe he was originally John Frank. I just received some information that said that people from KY actually had to sign up for the Confederate Army in Virginia but there doesn't seem to be any records left.
An interesting bit of information from an index of an 1888 newspaper article said that Frank and "William Wallace are the only members who live in Owensboro of the Dixie Guards that left Owensboro during the Civil War 27 years ago, most of company of about 50 were killed at the Battle of Bull Run."
The main reason I was redoubling my efforts to find a record is that I just recently found his grave plot in Owensboro, KY and he has no stone. I heard that Civil War veterans from both sides could have a military stone provided by the government if they had no stone. The catch is that only "official" records can be used to prove service despite photos, and articles.
Thanks again for your help!
