We moved back to TX in the early fall of 1959, and I haven't been back since. I've been a little afraid to go, actually - it must have changed enormously and I remember it as a truly great place for a kid to live. Uncle Walter kept the house at Valle Lake, and moved into it after he retired from Bell Telephone. The short north-south section of Russell Rd in section 23 runs through what looks to be just about the middle of that 80 acre tract. The year of this transaction is unknown, but we believe it was not later than 1850.
More research needs to be done to be certain.
