I bought an older home - and no joke - it says (written in the 1920's deed) that an owner of the property shall not sell his land to Jews.Not surprised and expect a similar restriction to exist in deeds concerning blacks, Irish, and others in various parts of the country. Read and understand deed restrictions before buying.
There is a regional park with a PGA golf course in my area that used to be the estate of an RJ Reynolds heir.
It was deeded to the County for use as a park for "white people only" in 1951.
