On the same page as my Retzlaff's in the book from The Triinity Church Historical Society there is listed two Eggert Families as departing from Prussia in 1843.
The names head of houses, children and spouses as well as the ages of each and occupation are listed. ( I only have is an abbreviated excerpt from the book).
The book is available for purchase from the Historical Society or available to be viewed at the Family History Center at Salt Lake City (was well as several other public libraries and/or genealogy libraries 'm sure).
I DO NOT HAVE A COPY OF THIS BOOK TO DO LOOKUPS-yet.
