Hi, Paula, Hattie Viola Lapp and William are indeed buried in the Dakota Cemetery. Hattie is the sister of my GGF. I have a picture of their entire family as well as quite a bit of history. E-mail me and I will be glad to share what I have with you. The father of Hattie and William Henry Lapp (my GGF) was a Mennonite minister in this area. I will wait to hear from you.
