You may want to try reading the sweetwater county wyoming census to locate the Philbrick family. You will find them posted on the US Gen-web project under the state of wyoming. I was a child living in daggett county in the 1950's and there was a Nels Philbrick who was married to Mabel Williamson he had sisters who lived in Green River, and one of the was Charolette who was married to Howard Petry. Another one was Pearl who was married to ? Zimmerman. I knew both of them. As for Alvin Schofeild there were only 2 familys living there at that time and I do not think that he was one of them.
