There are lots of Sawyer profiles on WikiTree.
I would suggest you begin by adding sources to Hubert which will give you information to populate profiles about his siblings, aunts and uncles, great aunts and uncles, etc. As you do this you will undoubtedly encounter existing profiles and thus profile managers who may be related.
To start searching for sources, from Hubert's profile pick the Research drop down menu, provide your WikiTree credentials and chose a site such as FamilySearch. You may have to remove some search criteria, or add other details you find from those sources. If you look at the image for his World War II draft registration it gives you the date and place of birth.
"United States World War II Draft Registration Cards, 1942," database with images, FamilySearch (https://familysearch.org/ark:/61903/1:1:V1VZ-KTW : 9 March 2018), Hubert Sawyer, 1942; citing NARA microfilm publication M1936, M1937, M1939, M1951, M1962, M1964, M1986, M2090, and M2097 (Washington D.C.: National Archives and Records Administration, n.d.).
Then you can find him with his siblings
