Surname Saturday - Joseph Geißler, A Difficult Man

In a previous post, I shared how difficult it was to find my grandfather Joseph Geißler in Columbus, Ohio between the years of 1850-1865. The more records I find about him, the more frustrating he becomes.

Let's review the first signature I noticed.

This one is on his marriage license in 1856.

(Interesting note: The 1856 marriage certificates in Franklin County, Ohio don't have much information about the person other than name, if they are of age, and the dates for the licenses. However, they do have the groom's signature which I find completely fascinating.)

Because of his many name variations, I have trouble deciding if I've found something pertaining to him or not. For instance, I have found a possible entry for Joseph Keizler or Keezler in the Consolidated Lists of Civil War Draft Registrations, but I can't prove that it is him.

I have had no luck finding him on a passenger list to determine where he came from. His naturalization certificate has him born in Baden. However, I can not find the paperwork that proceeded the certificate. Only the certificate that was has been passed down through the generations.

Joseph, dear Joseph, Where are you???? Where are you buried? When did you come to America and who are your Geißler family members?
