You don't want parents to be genetically related. If close relatives have kids, a Texas Chainsaw Massacre situation is likely to happen. Hint: They call that Wednesday in the city of London.
Just so you know, Texas Chainsaw Massacre was total fiction. Tobe made it all up.
The original house is in marble falls Texas and is Hoopers in marble falls. There is an identical house in Georgetown that is (I think still some facial surgery place off of the highway)
Years ago I wrote up the Texas chainsaw massacre road rally.
Bbq shack is south of Bastrop on 304 (haven’t been down there in 20 years) The location of the original house (moved to marble falls) was off of quick hill road in Round rock, which is apartments by a shipping center.
The Cemetary is in Leander Texas just west of town. It was in a 2 lane road 30 years ago, and now built up all around from what the map shows. At least that’s where I remember it.
I have my gps markers in a file somewhere.
But yeah, inbreeding causes issues. Ask lousania. Ask isreal
