Hi to you all,
I found a website that sells family history books and what makes it unique is that with each book comes a free searchable CD, no other site offer this kind of deal.
They have those books that I have been searching for a long time.
A Genealogical Sketch of the Preble Families. Resident in Portland Maine A. D. 1850 - by Preble, William Portland, ME , 1850
Preble of Machias (1771-1841) and His Descendants - by Jones, William P. Somerville, MA , 1929
Prebles in America with an Account of Abraham Preble the Emigrant Their Common Ancestor and of His Grandson Brigadier General Jedediah .. - by Preble, George H. Boston, MA , 1868
Check it out, it is worth it.
