Re: McCaskill/McKaskell Walther/Coleman Co./Santa anna
You may already have this - I see you have been looking at this family for some time.
In 1920 Walter McCaskill is in Leon Co., TX, living with C.W.C. Johnson, his brother-in-law.C.W. Scroggins is also in the household, listed as adopted son of Johnson.Nearby is a D.A. McCaskill, age 75, b. AL, who may be Walter's brother.
In 1910 Walter is living with C.W.C. Johnson.
I looked on familysearch.org and couldn't find a death record for Walter.You might check with the Coleman County clerk's office, or the state.
