Not easy researching surnames beginning with "Mc". A space between Mc and root name (Mc Cormick) has to be retrieved thusly. It depends on how the name was uploaded. Definitely McDonald with roots in KY, TN, AR, and TX. I submit the head-of-household in 1900 Stonewall was Thomas Green McDonald (7 Jul 1865 - 10 Aug 1950)? Further, believe the son was William Burl McDonald born 15 Aug 1898 per WWI Draft Registration-Polk, AR. Begin search in 1850 AR-Ouachita-Camden-Image 11 for W. A. Mc Donnell age 29 and born in KY. Next, 1860 TX-Johnson-Not Stated-Image 38 search for Wm A Mc Donald age 38. Then, 1870 TX-Hood-Not Stated-Image 32 look for Wm Mc Donals age 49. Note five-year old Thomas G.? View 1880 TX-Somervell-Precinct 3-District 148-Image 3 for Wm Mc Donald age 58. Struck out in 1910. Head back to 1920 AR-Polk-Ozark-Dist 110-Image 14 with Thomas Mc Donald age 54. Return to 1930 TX-Erath-Precinct 5-District 17-Image 13 with Thomas G. McDonald age 64. That's my 2-cents worth!
