I have thoroughly searched Our Huwe Heritage but have not found any Fred Max. I did find a son of Johann Ludwig, Otto who was born 7/20/1860 in Posen, Prussia, Germany. He died 5/3/1938 in Minot, ND, was married to Emma Krueger in Douglas Co., MN, before moving to South Dakota, eventually to ND.
Another Otto William Huwe, nephew of the first Otto, was born 7/23/1902 in Effington Township, Otter Tail Co., MN, died 6/1971 at St. Paul, MN. He was married to Mae Knoerl of Alexander, MN.
It appears our Huwe line is not the one you are looking for. There were already a few Huwe families in the States when ours arrived, so it may be one of them could be yours. If I run across any information on any of them, I will pass it along thru this forum. Be sure to look in periodically, as I don't have your e-mail address unless you write to me at firstname.lastname@example.org
