I am also researching this family. My connection is through the Yates family. Sadie Yates was my husband's great-aunt. I think I have found their sons Elmer, Raymond and Rex. Do you have any further information about death and burial of Lawrence and Sadie? I got the SSDI info on their sons, and wonder how they all ended up in Bremerton, Washington. I am happy to share info on Sarah's family.
