I am looking for descendants of Olaf and Olivia(Gibson) Arvidson who lived in the Riverside county area (Hemet?) from c1890-? They were Swedish. They had children Helena (she may have married a Brubaker) and Olaf P. and also Olivia's sister's son, Ross Anderson, who joined the family after 1920. I have found them listed in some voter registration lists but am looking for descendant to share information.
