Debra Timm Vandeloop, Donna Timm

Hi all, I'm an adoptee searching for info about my bmom who passed away in 96. Her name was Debra Leah Vandeloop, maiden name Timm. Her husband's name is Jefferey. Her sister's name is Donna. They lived in the Racine area, then outside of Appleton...any help/info suggestions would be wonderful. thanks, m26
