I can't find the Marion Collette you mention. I found two family trees with Sylvanus b. 1866, Smithfield, Cache, UT and died 1932 Vernal, Uintah, UT. He was married twice but neither wife was Lodema. Also he didn't have a child named Marion.
I DID find Marion College, b. abt. 1863 in Utah who in 1910 was living in Butte, Silver Bow, MT. Is he the Marion you're looking for?
