The profile you are linking to is for a person born over 400 years ago. Are you trying to prove a connection to Samuel Rutherford? If so, do you believe you're a direct male descendant (i.e. is your surname Rutherford)? If so, then you can take a Y-DNA test. There is at least one Rutherford DNA prject: https://www.familytreedna.com/groups/rutherford/about/background
If Samuel's isn't your direct paternal lineage and you're just trying to see if you are related, I don't think a genealogy test will help you in that respect (because it's over 400 years ago).
ISOGG.org has some good information about DNA: http://isogg.org/
