Sometimes a street just plain stumps me. This is one of those times. All I can tell you is that Livingston Drive, which runs along a long-gone segment of the Pacific Electric Railway, first appeared on a 1904 map of the Mira Mar tract – but whether it was named on the tract or earlier is unknown. The tract’s owners were Jotham Bixby and his distant cousin George C. Flint. There were no Livingstons in their family line(s), nor could I find a connection between them and any major locale called Livingston. Same with the tract’s sales agents Frank E. Shaw and H.S. Gundry. And I failed to dig up any Pacific Electric people named Livingston as well. So unless I discover anything more conclusive, let’s assume the name was chosen simply because it sounded upscale.
