The Humistonfamily bible has the marriage name of Jerome's mom and dad wilford parry and diena "hawes" humiston.
I did find the wm perry humiston. Jerome had a brother Samual. Perry's military has him listed as parry Humiston.
Jerome b.2/7/1862 d.2/21/1945 - Nancy b.9/10/1871 d.2/21/1965 Galien,MI. Nancy's parents: Lucius Chapel & Sarah or Sara "Aldrich" Chapel. Haven't been able to find anything on them. I don't have any further back than Parry.grandma and grandpa had only one child Jeanette m. 1911 to my grandfathe Teddy Watt-had 2 sons Kenneth & Harry (my dad)Berrien Co. Michigan
Thank you for you timely response and info.
