I'll try to help. Not related. You're right in 1900 she lived with Margart Wolfe and her son Elmer Wolfe born 1863. Actually he would be the age to be Arlie's father--except that in 1880 he was 17 still at home. Now at family search I did find that Elmer was the son of George Wolfe and Margaret Benner. I'll search a little more. If you haven't been to familysearch labs --try it.
