The sites you inquire about were named in honor of Cleophas Joseph Dowd (1856-1897). Dowd's grave, together with two ofhis children, are on his old Canyon Ranch inSheep Creek Canyon, south of Manila, Utah. I knew most of Dowd's children very well. His grandson, James O'Dowd (who adopted the old spelling of the name), died recently, but his widdow lives in California. I co-authored a manuscript on the Dowd family in conjunction with James O'Dowd. Will be glad to share any information.
