I am researching the HUGOBOOMs. If this is the Ross Hugoboom who was born abt 1888 in IA, he is the son of True and Kittie Blanch Everts Hugoboom. True was the son (or grandson) of Henry and Mary Harrington Hugoboom... (I have conflicting documentation.) Henry's father Hosea was the older brother of my GGG Grandfather Asa Hugoboom.
Earl Ross Hugoboom had 2 brothers Henry Carl (or Carl Henry) and Edwin True, both of whom ended up in Los Angeles, CA. (I have their obits on order.) He also had a sister Ethel. His father True died in 1930 in Neosho, Newton Co, MO.
Let me know what other information you might like.
