It may be possible to confirm family relationships with Charles by comparing test results with other carriers of his Y-chromosome or his mother's mitochondrial DNA.
However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share DNA with Charles:
Charles Franklin Smith's FindAGrave Memorial #135265033 shows a head stone naming Harry and Walter as his sons. This is CORRECT. They are out of his 3d wife Ellen Frances Green Smith [who is not listed on this head stone].
1 Mary Eliza Crowell - daughter Mertie E. Smith
2 Hannah Maria Nickerson - daughter Mabel Maria Smith
3 Ellen Frances Green - children Charlie M. Smith, Harry Smith, Walter Smith, Alice L. Smith, Mary E. Smith
I think the children listed on FindAGrave are for a different Charles Franklin Smith. https://www.findagrave.com/memorial/135265033 Wives and parents seem correct, supported by census data, but the daus Nelle, Mable and Alice seem to be all attached to the wrong father.
