Grandparents' cars. What American cars are these?

[540K]

My grandfather had a car dealership from 1913 until 1930. At various times he sold Ford, Studebaker, Maxwell, KRIT, Detroiter, Overland, Hupmobile and Hudson. Mostly he was a Ford agent though. Here is a photo of my grandfather about 1921, and my grandmother in July 1920. Any help identifying the cars would be appreciated. (At a glance it looks like my grandmother was showing some leg, but it's just the sun on the fender and shadows!)

First one is a T Ford, and the back of the second one looks like a Dodge I worked on for a friend.

The T is probably around 1919-1920.  I think the other one is a Hupmobile from 1915-1916.  This one has similarities    -   https://myntransportblog.files.wordpress.com/2015/12/1915-hupmobile.jpg?w=640
