Thank you! That first Mary is her. She is the daughter of Adin McDowell (founder of Adin).
Ora is her child. The baby son you mentioned is who I am related to. He was just a baby when his father died- Mary's husband. To my knowledge she never remarried. Some of the family moved to the Richmond area (her son and his wife and their kids).
We don't know much about her husband- he died young and since my uncle was a baby- he didn't know much and didn't pass much info down. The only info I have is from the county assessors history book of Modoc County- that's how I found out he owned a mine with a few other people and a stagecoach company.
