"W. Pluma Northcross, born July 21, 1887 in Delta Co., Texas; died September 17, 1980 in Tecumseh, Pottawatomie Co., Oklahoma; married Willie Drain June 24, 1912 in Oakland, Contra Costa Co., CA; died 1965."
I tried to do an online record search for Contra Costa County, but have not found any more information regarding William "Willie" Drain ...
If Glenn and Woodrow were brothers, perhaps then it was Jimmy who was a cousin of theirs.
Glenn would have died in the late 70s. He lived in Moore, OK. Loyd died in WWII (?) Chester was living around Norman, OK but not doing well last I knew (2006) Alene I vaguely remember, married to Tip. Unsure of whereabouts. Nettie was also in the Norman, OK area as of 2006. I do have her phone number, I will call her and see if she can be of help.
