My father, Richard M. Troxel, spent 46 years researching the Troxel (Troxell) family tree. Twenty years after he wrote his first book, "Troxel Trails" [which by the way sold out the entire production run], he updated it with new and corrected information in "Troxel(l) Tails and Trails." Since he is now 94 years old, he has moved to live with my sister's family. However, I have custody of the remaining copies of his book -- along with an addendum that takes our direct line back to 1527 to Peter Trachsel in Berne Canton, Switzerland.
If anyone is interested in obtaining one of the remaining copies of his book please email me at Troxel.Trails@gmail.com
