Here is where Ruth is stated as committing Suicide

In 1926, at age 8, Stanley discovered his mother’s body after she had committed suicide at the age of 26. Following his mother’s suicide, his father abandoned the family and Stanley and his older brother, Ralph Emerson Dunham, were sent to live with their maternal grandparents in El Dorado, Kansas.[7] A rebellious teenager, he allegedly punched his high school principal and spent some time drifting, hopping rail cars to Chicago, then California, then back again.[8] Stanley married Madelyn Payne on May 5, 1940, which was the night of Madelyn’s senior prom.[9]
Wikipedia isn’t exactly the most reliable source of material and they more than likely went by information from Jr’s fairy tale because further research pointed out that Ruth died of food poisoning the day after Thanksgiving and classmates of Stanley Armour all confirmed he did NOT have enough credits to graduate so had to return the following year to obtain the necessary credits to graduate. It comes down to trying to decide what is fact and what is fiction and when you have a group of classmates all agreeing Stanley Armour didn’t have enough credits to graduate I would tend to agree with them rather than Wikipedia which can be edited by anyone with that privilege. The same goes for the supposed suicide of Ruth Armour Dunham, when her obituary gave cause of death as food poisoning NOT suicide in a time when newspapers did not hesitate to inform the public if the deceased had committed suicide as per the article I posted upthread. People believed what Obama had been told by his grandfather, and that was clearly false, even the genealogists didn’t dig further or they would have discovered the difference!
