It may be possible to confirm family relationships with Spencer 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 Spencer:
John, unless there is a tombstone photo, all information on findagrave outside of what appears on a tombstone is heresay and no better than an online tree at ancestry.com or elsewhere. I don't use findagrave pages as a source unless there is a marker and then only what is actually on the marker. FYI
