Brewer Line to Franklin Pierce

Hi, I am trying to make a connection of the Brewer line to President Franklin Pierce. My only Brewer is hannah Brewer born 1630, she married Thomas Chandler who was born in England in 1630.Don't know when or where married. But he died 1703 in Andover, Massachusetts, and she died October 25, 1717.
I would like to find out her direct ancestors, as well as her link to President Pierce. Scott
