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.

  Descendants of Archibald McAllister of West Pennsboro Township, Cumberland, Co., Pa., 1730-1898 - by McAllister, Mary Catherine Harrisburg, PA , 1898 

Descendants of Col Alexander McAllister, etc. Genealogical Record of the Descendants of Col McAllister of Cumberland County, North Carolina. - by McAllister, D. S. Richmond, VA , 1946.
