William White, Sr. and son William Johnston White, Jr. (#17)
9-14-11: Yes! Finally we have identified the men as father and son, William White, Sr., who married Elizabeth Johnston, and his son William Johnston White, Jr.. A big thanks goes to cousin Margaret Haffner who supplied me with an earlier image of William J. White, Jr.. It was from this photograph that I was able to make the identification :-)
This image is from an original tintype photograph, taken ca. ?, which was scanned, emailed to me, and restored in 2005. The tintype image measures 2-3/8"x3-13/16".
