Vol. II of The Tower Genealogy is out of print. I have a copy and would be glad to do look ups for you. Our Tower Genealogical Society Newsletter editor has copies of Vol. III. I believe the price is $60.00. Also, TGS is having a reunion in 2009 in Hingham, MA. It will be the 400th Celebration of John Tower's Birthday. We would be happy to send you information.
