I am looking for death information on Patrick John (JP) McGill and his wife Alfrida (Frida) Augusta McGill (nee Brown). I located them living at San Juan Island, San Juan County, WA in 1910 along with two of their three sons Alton B McGill (age 5) and Leo M B McGill (age 3). Leo was born in Washington State according to the census. The couple had their 3rd son, James McGill in about 1911 in Washington. I have a possible death date for Alfrida of 15 Feb 1912. The kids are found in the 1920 census living with Patrick's mother Winifred McGill in Minnesota.
I checked the San Juan County cemeteries but there are no McGill's listed. I am not new to genealogy but new to Washington State resources. Any help would be most appreciated.
Thank you,

P.S. Patrick was born about 1879 in Canada, his wife Alfrida Brown was born in 7 January 1880 in Sweden.
