Wolter In South Dakota

I am leaving information for all that it may help and those who may help me. I have only been able to trace my history back to a Henry Wolter in South Dakota.

His Name was Henry Wolter and he was born in 1875, unknown place or to whom. He married Ida Walter (with an "A") in 1900. I still do not know when they moved to South Dakota or Henry's Parents. Henry and Ida had 7 children, Ed, Roy, Ralph, Melvin, Vera, Avis, and Viola. Ralph was born in March 12, 1913 and married Gertrude Gautheir on December 26, 1942 in Seattle. And then moved to Racine WI. Where they had Michael Henry Wolter in 1946, Ronald Samual Wolter in 1948 and Lynne Louis Wolter in 1956. Michael had a son in 1976, named Michael. Ronald had a daughter in the late 70's named Heather Wolter. Lynne had two children Kelly Wolter in 1974 and Joshua Wolter (myself) in 1983. Ralph Wolter passed in 1995 and Gertrude is still living and giving me much information as Is Avis. Hopefully this will help you, If you can help me please do.
