Welcome to Just Answer and thanks for requesting me. Was Neiswender Minnie's maiden name as well as her married name? Did she and Bert have children?
Sorry for the delay in explaining after opting out. I have a house full of company through the first of the week, so I really don't have the time to devote to the research that I need to spend. That's why I opted out so maybe someone else could help you. If the question is still open Tuesday evening, I may have time then to check. Meanwhile, anyone else is welcome to chime in. I am taking a calculated guess that REDMAN and ERDMAN(N) are the same surname, from West Prussia, with a couple of letters transposed. There were several families in Henry Co., IL using those surnames at the same time, and using similar first names. You may also want to check on whether Leopold (from the last question) was Carl/Karl Leopold if you have any of the German records.
Sorry it took so long to get back to you. My guests stayed an extra day.
According to Illinois marriage records, Bert Ellry NEISWENDER married Minnie T. ERDMAN 26 May 1909. The record is found in Henry County, Illinois marriage records, volume 3 p. 169, marriage license # XXXXX This is important because often the couples' parents are listed on the marriage license. I don't have access to the records but you can get them by following the link below. It has all the instructions you will need.

You can find further Erdman information here: http://sortedbyname.com/pages/e100360.html Use your browser to search for "Henry County."
In the 1900 census, 17-year-old Minnie T. Erdman was a servant in the home of Mr. & Mrs. XXXXX XXXXX in Munson Twp., Henry Co., IL. There were other young Erdmans who were also servants in several nearby townships within Henry Co.
The problem with Minnie being born in 1883 is that she isn't in the 1880 census with her parents, and the 1890 census was almost completely destroyed in a fire. By 1900 she was living on her own. There were too many Erdmans of the same age to determine which ones were her parents. Hopefully, you will find them listed on the marriage license.
You are so very welcome. It's good to know that Pauline and Minnie were sisters, so you know some of the siblings. Let me know if I can help further. Thanks so much for the accept and the lovely bonus. Happy holidays!
