I have about 8000 Humistons in my database and this is what I have:
Lewis Humiston married Ellen Amelia Humason.
His parents, Lawrence Stern Humiston and Ruth Tyler.
His siblings, Leonard, Susan, John Wesley, Stanley H., Mary, and Sylvia.
Ellen Amelia's parents, John Sykes Humiston and Vienna P. Golf.
If this is familiar, email me and we will get together and exchange information. I will share anything I have. My information comes from the Humiston Genealogy by Geo. and Louise Humiston.
