Legit vs. Suspect

Below are images of the alleged signature of Mr. Thelsey L. Fuller.

I believe the first image depicts the actual signature of Mr. Fuller.

As to the signatures depicted in the second image I believe the signatures to be suspect at best as they appear inconsistant when compared to the signature in the first image.

Keep in mind, the signature in the first image would have been made when Mr. Fuller was stronger, i.e. in better health than when he made the signatures in the second image.

Do all of these signatures appear to be made by the same person?
