I noticed that the transcribers of the 1910 Census had some difficulty deciphering the Laflin name, as I did. It appears as "Saflin" on Ancestry.com. At this time, Everett and his parents are still living in Watertown.
Everett's brother James Morrison is living in Seattle, Washington in 1910 with his wife of three years, Dorothy. He registered for the WW1 draft on September 12, 1918 in Cochise, Arizona. His occupation is listed as "credit man & bookkeeper" and his nearest relative was Caroline M. Laflin. I believe Caroline Laflin's maiden name may have been Cooksey, but a marriage record search would have to be done to confirm this.
Laflin isn't that common a name, but hopefully there are Laflin researchers out there who will enjoy seeing these photos.
