Myra Mae Wilmer Ehlebract

My grandmother was Myra Mae Ehlebract but she was born a Wilmer. She was born 11 June 1923 in Harvery, Illinois and died 16 December 1982 in McHenry, Illinois. Her mother Mildred Anderson married a Hank or George Wilmer, but they divorced. Later Mildred married Charles Ehlebract when Myra was 3 years Charles adopted her. Any info on her father Wilmer would be grateful. I would be very interested in getting in touch with living relatives of Mrya's father.
