In the Burnet County History, Vol 2, p. 246, there is mention of Robert L. and Mary M. Phillips, both born on the Phillips Ranch west of Marble Falls. There children were Wendal Lee, b. 20 Mar 1904, J. R., b. 2 oct 1908. These are the descendents of John Rufus Phillips of Llano County and Susan Alice Tate of Nacogdoches County. John's father was Benjamin M. Phillips m. Melissa Crownover. The only thing I caught was the ranch match up with your location. I will continue to look in Williamson County next.
