Genealogy is the second most popular hobby in the United States after gardening. A search for "genealogy" in [...]'s book directory finds over 60,000 results! Many of these books on genealogy are outstanding resources. However, very few of these books are about East Frisian genealogy. In fact, a search for "Friesland genealogy" finds four books concerning the Banta family's genealogy, a book about a missing uncle in Nazi-occupied Holland, and Groenhagen Family History, which Kevin Groenhagen, the author of this book, published in 2020.

Realizing there are few books that specifically cover the unique intricacies of East Frisian genealogy, Groenhagen decided to share what he has learned about East Frisian genealogy during the past 30 years.

In Finding Your East Frisian Ancestors and Cousins, Groenhagen discusses techniques and sources you can use to find your ancestors and cousins in both the United States and East Friesland. Groenhagen shares online and print resources he used to find his own ancestors and cousins, discusses the practice of patronymics, and includes a chapter on genetic genealogy, which has introduced science to the art of genealogy.

Groenhagen also includes a chapter on how to write and publish a book about your ancestors and cousins after you have done your research.
