Starting Sept. 30, 2014, Genealogy.com will be making a big change. GenForum
message boards, Family Tree Maker homepages, and the most popular articles
will be preserved in a read-only format, while several other features will
no longer be available, including member subscriptions and the Shop.
At www.ourroots.com you can search for these families. For instance in the local history book, "Old & new furrows : the story of Rosthern" on page 474 there is mention of the birthyears of the couple from Prussia. In the search area you can enter, loewen, or esau, etc. and you will find siblings of offspring, photos and stories.
Also check out, "Our heritage : a view from the Butte. Volume 2", pages 588-589 for the Esau people.
Even, "Footprints on Mi-Chig-Wun : memoirs of Sunnyslope pioneers", p.306, mentions Esau and Loewen names with a connection to Oklahoma.
