As it so happens, the Russell memorial has a double stone and the volunteer (Sarah Carter) posted the information for Thad Allma Russell...notice the middle name change from Allan to Allma. The bonus? The grave stone includes a marriage date, which means yet another piece of paper to chase.
Getting corrections like Thad's middle name (or at least a new fact like a marriage date to ponder) is another benefit to supporting and participating in FAG. Anyway, for anyone searching for Thad Allma Russell, you can find him at Tuscola Cemetery, Tuscola, Taylor County, Texas. His FAG memorial is 87398568.
Now the fun part. I've found a newspaper article indicating that Lucy and Thad were divorced. Here it is.
The Abilene Reporter-News, Abilene, Texas, 22 Jun 1962, Page 36
Thad A. Russell v. Lucy J. Russell, plaintiff granted divorce.
And yet, they have a double stone and are buried as man and wife with nary a mention of a divorce.
So what's the story? Did they reconcile? Did they remarry? Do you know? Will you tell?
