Mark Scobell, Myrtle Scobell, and George Edward Scobell
Mark Scobell, Myrtle Scobell and George Edward Scobell, Jr. This was not ID'd so it's my best guess at this time.
I think these are Scobell kids, Mark, Myrtle and George Edward Jr.. Mark was the son of George Edward Scobell and his 2nd wife Margaret Elizabeth McLin. Myrtle and George Edward Jr. were his sons by his first wife Bertha Sallach.
