For what it's worth, and since it's such an unusual name, I had a brilliant math teacher named Arnie Krivitzky (spelling uncertain) in Brooklyn in the late 1960s (ugh). When I lost track of them he and his wife had one daughter, ?Laura Hope?
Last time I checked they were on Spokeo so they should be traceable. At that time they had addresses in New Jersey and Delray, Florida.
