Thank you so much for posting this obit! I am helping someone in the Netherlands who is related to this William DeVries (birth name: Wietse de Vries). He had been searching for quite sometime to find William and his sister, Jennie (birth name: Janke de Vries).
I hope you take the time to correct William's birthdate (9 October 1896) on your Ancestry.com tree. That will make it easier for people who are searching for this individual in light of the fact there was another William DeVries who was born in 1889 (the year you have listed).
Would you happen to have or know where to obtain the obit for William's sister, Jennie Reiser? She lived in Tripp, SD per William's obit. She died on 3 February 1981 in Tripp and is buried in the Grace Hill Cemetery, Tripp, Hutchinson Cemetery, SD.
Thanks again for the obit of William and any other help you may give me!
