American Indian Historical Society (AIHS) founding date
I noticed the American Indian Historical Society (AIHS) founding date mentioned in this WP article as 1950, but on the Jeannette Henry Costo page it reads as 1962. Both dates appear to have RS citations also. Which is it? PigeonChickenFish (talk) 02:43, 27 August 2022 (UTC)
