These brothers John W and George W Andrew apparently married sisters Nancy and Ann Eliza Downs.   John and George appear to be sons of Cyrus and Clarissa (Shepard) Andrew.  James and Phebe (Shaw) Downs are parents of Nancy and Ann.  This will require more checking for confirmation.  Living in adjacent households in 1870.
