I am researching the same Gleasons. My great-grandmother is Irma Gleason, Alexander's ninth child. I have photographs also. Alexander Gleason and Jennetta (Thompson) had nine children. Leo, Almond, Andrew, Philander, Lancelot(Dan), Opal, Dolly(Dot), Fanny(Juanita), and Irma. My grandmother is Irma's daughter and she is still alive. She and my mother knew Lancelot(Dan)well. Please get me any information that you have. I will continue to give you my info. as you need it.
