Accorging to the book that I have, Anna was Anthony Jacob's mother, not his wife. According to this book Herr George HENCKEL(1635-29 Jan 1678) m. Anna Eulalia DENTZER (1640-1700). They marred 2 May 1666 at Steinber, Germany. She was the daughter of Othmar and Louisa (Wagner) DENTZER. Herr and Anna had six children.Anthony Jacob being one of them. He is listed as Anthonius Jacobus HENCKEL, baptized 27 Oct 1668 Mehrenberg Lutheran Church.
Reverend Anthony Jacob HENCKEL was the emigrant ancestor and progenitor of the families in this genealogy.
It has another couple generations back on both the HENCKEL and DENTZER lines.
This book says that Anthony Jacob HENCKEL also married a DENTZER. Maria Elizabeth DENTZER.
Anthony and Maria Elizabeth HENCKEL had 12 children. Do you have the info on these children?.. they are all listed in the book with many of their descendants. All 12 children were born in Daudenzell, Germany
This book has so much info on this family, since the book is about Anthony and his descendants. Perhaps you could check a local LDS Family History Center, it is available to order on loan, on film.
