Kendal has a few surviving square greens. Most were redesigned in-situ, or in new locations (with the originals surviving as part of the fairway), as per USGA specs. during the late 1990s / early 2000s. Probably for the best, they ran out of money.
Out of character with the remainder of the course, the 12th at Elderslie is seriously squared.
The common denominator appears to be steep/hilly terrain...function before form!
