Re: Alexander Marcus/John Paxton connection?
Why must there be a link? At most they're two people who resemble each other somewhat despite living a century apart. You may as well ask if Captain Ron Tracey and Dr. Simon Van Gelder are related, or whether Dr. Ann Mulhall is a relative of Dr. Katherine Pulaski.
Agreed. You might as well ask if James T. Kirk is related to T. J. Hooker and a guy who saw a gremlin on an airplane wing, since they all resemble each other.
