I have finished entering the family data for the first six generations of the Gallup family from the following book.
Gallup Genealogy: Gallop, Galloup, Galloupe, Gallupe, Gollop. Second edition, Revised and Expanded. By The Gallup Family Association, Inc. Brigham Young University, Family History and Genealogy Research Services, Provo, Utah. 1987.
I also copied generation 7 and 8 and may add those later.
