Thought I would add what I found that wasn't listed on the ancestry tree.

Rosa Gremel married Robert Robinson in Osceola, Michigan.
Rosa's father is listed as Andrew Gremel. Robert's parents are listed as Robert Robinson & Annie Courtney. I found Howard's WWI draft card. He lists his middle name as Courtney. Must be for his mother's maiden name. Howard is buried in Ft. Logan National Cemetery in Denver. According to what I found his wife Lorena R Robinson is buried with him. A second wife?
