Looking for Amelia Millie Milley Higgins Higgens IN Jennings County Indiana

I am trying to find out more about my GGG Grandmother Millie Higgins Spencer. I know she got married in Jennings County Indiana to my GGG Grandfather Robert Spencer. Her parents were Walter and Catharine Higgins. I am trying to find out more about them and where they came from and who their parents are. I want to find out more about him as well. I have a picture of Millie ( standing ) with my grandmother Dorothy Tritch ( she is the baby ) and her son my GG Grandfather Harry Spencer and my GG Grandmother Dora Hipp Spencer. This picture is taken in Indianapolis, IN.
