Looking for Dugal Black Relations May Have MI Connections

My paternal grandfather was Dugal Edward Black, son of George and Hattie (Butler) Black, born 5/25/1900, died 12/15/1931 in Lansing, MI. He had 2 sisters, Amelia and Nellie, and 2 brothers, Archie and Milton. Dugal married Bernice G. Parrish. They had 3 children, Emma, Neida, and Wayne (my Dad). He passed away when my dad and aunts were young. Unfortunately, we don't have a lot more to go on. Any help you can give would be greatly appreciated. Thanks!
