I dont know if youll ever see this or if your post ever found answers to your mother but here goes. Your grandparents were most likely thomas b and evelyn egdahl of superior if your birth mother was unmarried and from douglas county Wisconsin. Theres no other listed egdahls in that area but i figured having grandparents might help you find their childrens information. You're not likely related to the schofield. Based egfahls/agdahl because of the grandparents generation for you there was inly two surving males stanley and Clarence. Clarence had one surving daughter whod be around the right age to be your burth mom but to my knowledge she didnt have more than one surving son having had many difficulties with her children so i doubt shed have given up a healthy child. Her name was guinn. Of Stanley's children i dont know.
