Tom Hanks connection to Abraham Lincoln via the Hanks family

According to the IMDB page for Tom Hanks:
http://www.imdb.com/name/nm0000158/bio

"He is a third cousin, four generations removed, of former U.S. President Abraham Lincoln. Their common ancestor is John Hanks (1680 - 1740), who was the great-great-grandfather of Lincoln, and the great-great-great-great-great-great-grandfather of Tom Hanks."

John Hanks, Sr. is Tom Hanks' 6th g-grandfather here on geni, so far so good.

William Hanks, Jr is Abraham Lincoln's 2nd g-grandfather on geni though.

Thoughts?

Often wonder were the connction was with Tom Hanks our family is also related to Lincoln on my mothers's side her grandma Frances Reed- Andrus and g grandma Andrus's mother was a Hanks we think that her first name was Hannah.
