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.
The Yale family or The descendants of David Yale: with genealogical notices of each family - by Yale, Elihu New Haven, CT , 1850
Yale Genealogy and History of Wales. The British Kings and Princes; Life of Owen Glyndwr; Biographies of Governor Elihu Yale to Whom Yale Univ….. - by Yale, Rodney H. Beatrice, NE , 1908
Check it out, it is worth it.
