What dates are we talking? I found a public tree with an August Sylvester Lemmens married to Rosetta Florence Miller. There is a child, William David Lemmens Schaufelberger, who was born in 1940. This tree is unsourced, but it has the parents of August Lemmens and Rosetta Miller and a marriage of Rosetta to Alex Schaufelberger.
I've been sourcing this family and found a Find A Grave memorial for August's father, Alphonse Lemmens, which includes a photo of him. http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GSln=LEM&GSpartial=1&GSbyrel=all&GSst=51&GScntry=4&GSsr=1961&GRid=95301842&
There are many records available for this family, it doesn't have to be unsourced. The name is Lemmens and they were from Belgium, with August born in Lincoln County, Wisconsin in 1913. The answers and documents you need to prove this tree are on Ancestry.com. If you'd like to join the public tree I've made for them, send me your email address. You'll be able to take the tree over and make any changes you'd like.
