Upon further review (by my sister, who is more the family history expert), this picture is misidentified. Our best guess is that one of the children might be our grandmother, given that both appear to be girls.
My mother is Pamela Thompson. My dad is Richard William Russell. My mom grew up in Fenwick Michigan. My dad grew up in Hart Michigan. They had 2 kids together. Living in Michigan. I have other Half siblings out there somewhere
