You could try city directories from the period, though it would require browsing through them to see if you can locate a Peter with an Elise, or a Roland, etc. I see that the Charles F. Cummings New Jersey Information Center at the Newark Public Library in NJ has copies of city directories for West Long Branch for the period 1961-1965. See https://npl.org/collections-services/charles-f-cummings-new-jersey-information-center/guide-to-nj-city-directories/ The NY Public Library also has Monmouth County white pages from that time period.
Unfortunately, none of these directories appear to be accessible online.
