Yes, the 1892 reference is likely. I never found him in the 1891 census but he's in the 1901 census. I also think I have an obit for one or both of them....need to double check. My great grandfather Ralph Ashbrook Olsen lived in his father's house all his life. He lived into his 90s. He died maybe a decade ago so some items from Sarah and Seren were still in the house.
