Apparently there are more -- or closer -- connections between the Kobels and the Deans than you were aware of! Some of these people may be related to both sides of your paternal ancestry.
You can use 23andMe's DNA comparison tools to try to narrow down the connections with your DNA relatives. If you know the relationship to one of your DNA relatives (for example, a first cousin), look at your other "relatives in common" with that known relative. When you and your known relative have a relative in common and the three of you have a match on the same DNA segment, there's a good chance that the third person is related to you on the same side of your family as your known relative.
A number of my 23andMe DNA Relatives match on the X chromosome -- often only on the X chromosome. If you find an X chromosome match, you as a male can be reasonably sure that the match is on your mother's side. The "X chromosome" section on your WikiTree Family Tree and Tools page will give you more information on who a particular person could have inherited parts of their X chromosome from.
Also, you can compare 23andMe's Y-chromosome haplogroup determinations to help narrow down the relationships. If you find a DNA relative named Dean who shares your Y haplogroup, it's possible that you both descend from the same Dean paternal line (more refined testing would be needed to verify this). If you don't share a Y haplogroup with another Dean, you can be pretty sure you aren't related on the paternal line.
