Looking for Robert Clayton of New York Oregon

Robert D. Clayton was my Grandfather, born in New York, married Eloise Bennett of Wisconsin and settled in Oregon. He died in Oregon in 1952. When Eloise died, he married Maude ?? in Oregon. His Dad (Robert Clayton) was from New York and his Mother was possibly from Pennsylvania. He was supposedly in an orphanage in New York. Any information would greatly be appreciated. Thank you.
