Some effort goes into tracing the genealogy of national figures. Reading this report, I found something noteworthy about John McCain.
It seems "John Coddington" of the 1600's is John McCain's
great-great-great-great-great-great-great-great-great grandfather through three separate
lineages. That means some cousins married at some point in the past 400 years of McCain
history. John McCain: If we can't trust his cousins not to marry, how can we trust him to
kick the special interests out of Washington?
