The Allen family has played a significant role in both British and American history, with members contributing in times of war and peace. Recognized among the “best families” by the American Historical-Genealogical Society, the Allens have a long lineage traced back to Alan Fergeant, Count of Brittany. Variations of the surname include Alleine, Alleyne, and Allin. This volume compiles genealogical records, omitting certain branches without issue, and offers insights into prominent Allens across generations. It includes details on notable individuals, early settlers, and those who participated in the American Revolution. Researchers are encouraged to consult referenced sources for further study.
