Irvin L. Shuler?

This is a cased 2" x 2.5" ambrotype, most likely taken about 1860.  The image is poor quality and rather badly out of focus. It is mounted in a Union Case with a square aperture copper frame.

This photograph was in the personal effects of Ellen Hydrick and is assumed to be of her grandfather, Irvin Shuler. Irvin was 37 years old in 1860
